Another top notch and money saving review Tim ⭐⭐⭐⭐⭐ It's great to have a reviewer that can't be 'bought' ITWT ✅ Shame you can't get the Fast R in your size ☹️ Would love to see your shoe off Vs VF ...but I recon I know the answer ☺️
I think I may be the first RU-vidr to do anything with this Next Gen Stryd. I sort of get the feeling they don't send them out "for review" so maybe not so many want to buy one to do so. I saw one video of the NEXT% 2 vs FAST-R. Apparently the FAST-R is "great" (or similar) but it did not seem the choice of shoe for an upcoming marathon so I figured it was effectively an honourable loser. I eventually got the Deviate Nitro Elite and that was merely "OK" IMHO. Hard to see this would "beat" the NEXT% and I have just picked 2 pairs of the NEXT% 2 for pretty much the same price as the Puma one is going for.
@@TimGrose yes the runtesters said the Puma DNE and FastR were similar I tried the DNE at Start fitness and it felt very similar to my Saucony Endorphin pro1.. good but not special. It's just I'm on my 3rd pair of Tempo next% and I like doing easy runs in that shoe but nothing fast as it feels too big and heavy.. I thought and Ed Budd said the Fast R was similar to the tempo next% so I thought with it been lighter it might work well for me 🤔 Will wait till it's discounted 😁
My next gen V4 arrived on Monday and I've run with it a few times now. It's certainly showing a lot more air power than with stryd wind has last few months. 5 to 9% rather than 0 to 3% of late, however looking back to similar runs from last year it used to see 3 to 7% . Either the air port has been obscured don't think that is true on visual check or the algorithm was amended with the firmware update. Certainly with vaporfly2 offset lacing I've had very low to zero air power. Keep up the good work on the review, and hopefully you can get back to racing well again
Yeah when I first got the older Stryd Wind it seemed to give more Air Power than it did not long after. I haven’t actually ran in overly windy conditions yet so the most have seen even in parts of runs is about 6% but certainly I never got 3-5% averages just going fairly easy on fairly calm days.
Ha ha, I kind of "gave up" with that after numerous engagements with Stryd. Customer is normally always right normally except with Stryd when it is the other way round in the main. Oddly one of my very first RU-vid videos was a comparison of the wind detection in the new Stryd Wind with Garmin's implementation using weather forecasts. The Stryd Wind did seem to "work" then but after a firmware upgrade or two and passage of time I was usually, as here, back to 1% (at best) Air Power even when running fairly fast on days with clearly some actual wind.
I have one of the early non wind Stryd's and found the next gen one to be a big step up in terms of responsiveness, (which is useful doing shorter reps on the track) and I find the wind feature really useful for maintaining a steady power output. I do tend to set the device, Apple Watch or Garmin 245 to give me a three second average, so that helps with smoothing out the figure showing on the display. The 'Impact Loading Rate' is supposed to represent the impact forces going through your legs, hips etc. I found it to be quite useful, in that hill repeats show less impact loading than running on the flat at the same power. Also changing surfaces, from tarmac to grass, I also saw a corresponding drop in impact loading rate. So, although Stryd don't provide a lot of info on how to use this, I see this as a potentially useful feature to avoid injury, by monitoring how changing the surfaces you run on, or using inclines reduce impact. At the moment there is no weekly cumulative figure, but presumably this is something Stryd will work on over time, to make this feature more useful. Overall I have found the Stryd to be very useful, and more accurate and consistent than GPS, for both distance and pace. And of course, it is useful on the treadmill.
I have been using a 10 second average which seems reasonably stable when am doing steady state runs as such. Yeah I think the non wind one straight to the Next Gen would be a good upgrade as the Air Power calculation/detection now seems somewhat better. I am not too bothered about responsiveness for track reps as would just look at my times there but a useful upgrade none the less. With Multi Band GPS on the Forerunner 955 I do find taking distance and pace from the Stryd now largely redundant but useful on a treadmill especially if not on my own one with transmits its speed to say Zwift over Bluetooth.
@@TimGrose I have a Garmin Forerunner 245 and I tried all combinations of GPS, but still found some routes had problems. Eg. running down by the Thames, they still have me running in the water, especially with tall buildings around or lots of trees. So I find the Stryd more reliable than GPS. Is it watch dependent, are some better than others?
Interesting to see your Stryd info Tim, I found my air power worked very well until I lost it (in some kind of sleep deprived state I think I threw it in the bin by accident). On the fence about replacing it and whether it's really worth it. I'm certainly not convinced the new one is any kind of worthwhile upgrade over the old one. Also I did actually look at my power during sprints, but purely to make sure I wasn't overdoing it on doing some strides before a session, but that really isn't an upgrade I'd need!
Yeah I have to admit I haven't been using my Stryd very often in recent times. I think that is partly as unless you are doing something "hard" (or testing something!) it serves no real purpose. Plenty of ways not to run too hard on easy days of course. Even when I do use it, I still don't look at the power too often. That said it is interesting to look at after runs. I guess you want a Stryd anything this new one is no more expensive and an incremental improvement. That said it remains another thing to remember and indeed charge and I kind of prefer just to look down at my shoes and feet "as is" as it were. It is similar with Garmin power which is always there now but then got have a different set of numbers to consider.
Thanks for this Tim. I use power for my training and usefully this week is a testing week so I will have a “next gen” CP by the end of the week. Did one run with it and I’m estimating between a 5-6% increase in measured CP.
I need to dig a bit more but on my 2 runs so far, I was getting more power (which will of course get a higher CP) primarily as I was getting somewhat more Air Power. What did you see there?
@@TimGrose I didn’t wear both as you did. But I agree I am seeing more realistic and consistent wind power contributions. On similar runs from a 1% average up to a 4% average. My gut is that there is a little bit of something else going on as well in it catching more transients, but perhaps that is the engineer in me.
@@SpikeBrookes87 yeah I think you are right then the new one might report slightly higher anyway. I thought I had set both to my "current" weight of 72 kg but it is possible the older Stryd Wind might have been a fraction less as I used to use 71 kg but thought I would rebase everything going forwards. I have now setup the new and old on different Stryd accounts and setup the Stryd app on 2 phones so I can keep them independent as it were. That said the vast part of the difference in my race was clearly Air Power and obviously that would give you a higher CP not by being fitter/better but just because of that different detection.
Technically I’m pleased that we are getting better measurements. But given running with power is all about relative and % of CP, various aspects are going to be thrown off for a period. For instance I do find reasonable value in the Stryd race planner but that will be useless for a while as Stryd will presumably assume I got faster but actually in the model I got less efficient.
@@SpikeBrookes87 yeah agree. When I did my last sub 3 marathon I thought I was needing around 290W. That's now looking a bit low and be now at least 300W I think. Be good to test the new one on a very windy day as although it was an exposed course for my race here, the wind wasn't actually too bad.
Hi Tim. I've had my new Stryd Next Gen for just over a week. I've had to apply a calibration factor of 103.5 on my Garmin watch because the Stryd was measuring short. It seems accurate now at my normal easy pace. Do you know if this accuracy will hold at all paces, or only at a certain pace, much like and old fashioned pedometer?
Yeah I have found it is reasonably consistent over different paces. TBH though Multi Band GPS on devices like the Forerunner 955 or 965 has rendered the Stryd redundant for me for pace/speed outdoors and I kind got tired as it were of Power anyway largely due to Air Power variance so I haven’t used my Stryd for sometime now. Hope you find it more useful ?
Thanks Tim, I appreciate the reply. Seems to be working so far for me. I raced a Parkrun the second time I used it and got a critical power number afterwards. Going by their zones, I was doing my easy runs too quickly. I was running in the Stryd moderate zone. If it prevents just one injury it's money well spent.
@@steveaye5427 that's good. Over the years of using it I have realised it is "OK" to say slow down uphill as you are still working hard, if not harder than you think despite what the pace says. And yeah sure we all are guilty sometimes of thinking are easy runs are really easy when often they are not so anything that helps remind you of that is useful. I just think after a while I can just gauge that anyway.
Thanks for the view and next generation stryd compared to the wind one. You discussed how the power is higher with the new one consistently. I assume that your pace is the same, but I think you said that you were only using the stryd for power and not pace/distance. Can you confirm/comment? I am curious because my wind one seems off and has for a long time, so I am looking to see if I should get the new one for greater accuracy.
Since this video, Stryd have issued an updated firmware for the Next Gen which largely seems to have reduced the Air Power to similar levels I was getting with the previous Stryd Wind. That accounts for most of the difference but the "raw" power does still seem a little higher than before. Yeah I only use Stryd for power and largely always have done. Multi Band GPS in the newer watches like the Forerunner 955 I have has been a big game changer and I think now only might have some advantage "indoors". Foot pods always seem to need a calibration factor applied that seems to differ device to device. My Next Gen seems to need about 101.5% so it is certainly not of "greater accuracy" for pace/distance out of the box if that is what you mean. As for the power, I think it just needs to be personal to you with the same device. I hadn't used my Stryd Wind largely since this race so now everything is coming from the Next Gen one. It is hard for me that the "upgrade" is really that necessary unless you just want a new one. It still basically works the same IMHO.
Thx Tim. Do you think continue to use Stryd? Or are you happy with the Multi band 955? One of my issues is that I've been using Stryd for years. So it's hard to leave that ecosystem., at least as another metric partner in my training. And it does come in handy during the big city marathons when GPS is dicey.
More than happy with Multi Band on the 955 for pace/distance and the "faff factor" is so much less. TBH I was fine with pace/distance from my previous 945 so never used Stryd for that anyway - well at least outdoors. I think will probably use Stryd going forward like I have been of late - for some of my harder runs. Most days for easy base miles there are plenty of ways of stopping me going too quick. RPE being good enough. One of the drawbacks with Stryd is that I never found it tells me much about runs that aren't too hard because, unlike HR, it can't really tell me how close I am to my limit that day as it were.
Great content as always Tim. How do you calibrate your Stryd? I've just left mine at 100 as stated by Stryd. Not sure if it's worth splashing out for the small increases in responsiveness. I'm sure I'll cave in at some point.
So far, I have just observed what the auto calibration on my Forerunner 955 says. Given my 10 mile race came up 9.99 miles by GPS, there is clearly no need to use Stryd where I normally run. That came up 101.3% and subsequent ones and on another Forerunner varied between 101.3% and 101.7%. I tried to take pace/distance with it set to 101.3% on another Forerunner to my 955 yesterday and over 8 miles the two were only 0.02 miles out. So it seems both methods "work" but I do feel Multi Band GPS on the 955 has rendered taking the pace/distance from a Stryd redundant - well at least for me although TBH I never did anyway.
@@TimGrose Die Autokalibration sollte gar nicht verwendet werden. Ich besitze die fenix 7 und laufe nur mit Stryd, nicht wegen GPS sondern wegen schnellerer Reaktion bei Intervallen und mehr Genauigkeit im dichten Wald, Unterführungen und natürlich auf dem Band.
My primary reason for having a STRYD is for the treadmill. There’s really nothing better. I’m considering the upgrade because of the improved responsiveness. There’s always been a 5-10 second delay in regards to pace for the first mile or so with the original STRYD wind. Glad to hear that’s been fixed with the new model. However I’m curious as to why that couldn’t be fixed with a firmware update. Great video.
I will have to try it on the treadmill. I don't have much real use it for there as my Technogym MYRUN transmits its speed to Zwift over Bluetooth so I can get both to match and the reported speed is realistic enough. Agree though that it is the best foot pod for treadmill use although there isn't really any credible alternative anyway. I guess there is only so much you can do in software. Imagine it has faster processors etc etc.
How does this work with a treadmill actually?? Does it need to be. Certain type treadmill, calibration? Does it just measure cadence and take a rough estimate on distance covered? I've always been tempted to purchase a STRYD but very mixed reviews, wondered how accurate it would be regarding predicted Finish times etc etc
@@earlybhoy1119 Stryd doesn't really "know" if you are on a treadmill or outdoors so it is just effectively "measuring" pace from its own sensors. How it actually does that is obviously only known by Stryd. If you want to try and match what Stryd gives to your treadmill you basically apply a calibration factor which just scales the pace. Typically Stryd measures less than the treadmill as they apparently don't "count" the periods where you are "airborne" but the belt is still going. There has been a lot of discussion as to whether that is "correct" but ultimately I view treadmill running as just a decent chance for a run when can't go outside and it will certainly give you a very good idea of your pace and distance.
Tyrese if your treadmill doesn’t have it built in like Tims, then I found the NPE Runn sensor is much better than Stryd for Zwift. More reliable and stays on the treadmill so other family members can use whenever they like.
Thanks for doing this. I just upgraded. It’s nice but not sure I notice much of a difference yet. There is supposedly some new impact load rate which I have not found yet.
I can see impact load rate on my activity within the web browser version of the Power Center. Not sure what you are meant to do with it however. It seems to get higher when I go faster/try harder but then so usually does power and pace and probably HR too! Oddly today both that impact load rate and Air Power cut out half way into the run. Yeah TBH I only really got the new one as I figured I could not continue to use the old one in my videos alongside new Garmins and new shoes as need to keep up with the latest "stuff" to be able to comment usefully on using it all in tandem as it were.
I've looked at the Stryd things a few times and wondered whether it would be worth getting one. I guess that, as you suggest, they vary from unit to unit even within the same model and generation. So realistically it's a case of using any datum as a benchmark and measuring performance changes against that. I've only raced at 10 miles twice, one at the Jelly Tea (Tynedale Harriers) and recently the Brampton to Carlisle 10 Miles. 68:16 seems like a decent time considering illness/recovery etc. I managed 69:26 at Brampton which was a PB, and not bad for a V55 (only just over a year left). After all that, I enjoyed this even though some of it baffled me - but I do love a good set of running stats 😀
To be fair each Stryd that I have tried has been consistent with itself run to run and I guess most runners will only have one! I have used Stryd now for about 5 years on and off but still not really "sold" on power as pace normally works well enough for me but I do like more stats to look at! Yeah 10 mile races aren't so common these days but it is quite a good distance as can treat it a bit like a long 10K.
I have the new Styd for a week. I don't understand a few of the metrics. Leg Stiffness LLS is higher better? Today I run fast and it was 13 in my RC Elite V2.. Yesterday in Tempus it was 9 ? Yesterday Form Power was 60 but today fast run was 66 ? What is better? The faster I run the higher the Form Power.. Help 🙄
Yeah have to admit to not paying much attention to LSS or Form Power. Recall somebody saying my LSS is "high" and apparently good but clearly there were way faster fellow masters running in this race so not exactly "helping" !
@@cakej1 and jokingly I had sort of pondered the opposite - if I am "stiff as a board" after a hard race like here and/or not going any S&C I might get a higher LSS. Otherwise day to day I shall keep an eye on it and see if it tells me anything. I am doubtful.
One would think that the newer Stryd unit polling more frequently would result in more accurate AP over time. I know my AP numbers can wildly vary even over the same section of ground with similar "feeling" wind speeds. Also, given the slanted lacing of the Nike "Fly" shoes it can be really difficult to get consistent AP measurements when doing the double shoe comparison. I like my Stryd wind version, I'm still on the fence about upgrading. Since I just don't feel I need that extra level of responsiveness. New Impact metric is said to quantify lower body stress per run, such as additional load from downhill running and speed intervals. Assuming it feeds into higher RSS numbers for those runs where you are exerting more impact force.
Looking at some more at my run today in reported wind of just 1 mph, I now wonder if Stryd is just adding "background" Air Power in the new one as I again mostly got 4% on average and scanning the graph it was nearly always between 3 and 5%. The Stryd Wind "as normal" got 1% on average again. Today in just "normal" Nike Pegasus shoes so is the "offset" lacing just a red herring. I also swopped feet today so the new one was on right not left as in my first two runs. That lower body stress today was 62 after 8 relatively slow miles so a similar time to 10 miles at race effort when got 73. Neither flat but equally neither massively downhill or uphill at any point.
@@TimGrose It's why I'm going to wait a bit, see some more reviews, perhaps a few firmware updates. Since the level of accuracy my current Stryd provides suits my needs.
Regarding the wind.. I run this morning and it was windy and the power went up by about 10 percent with about a second delay every time I hit a wind gush.. But of course it does not know when you have tail wind..
Ah interesting. Did you notice that change on your watch on your run and/or later when looking at the data? I always thought it would be useful for Stryd to be able to show you Air Power on its own as an alternative data field. I have 10 sec average power and lap power set at the moment.
@@TimGrose I only saw it live on the Garmin 745. I did not check on the computer. Only in the app on the phone and I don't think they show it separately from the standard energy number. It did not get 100 percent I think but did react most times I faced the wind.
Nice running Tim. After the period out due to illness you’ve had it’s a good rust buster and will help the fitness. Bainesy strikes again! World M50 half marathon champ and now British M50 10 mile champ. Next weekend probably British M50 5k champ too… I’ll be happy just being at the start of the final straight while he finishes! Yeah, your test proves the Stryd Wind wasn’t very good at detecting, erm, wind. But what we all really wanted to know is whether the next gen unit was made of higher quality materials and looked and felt more pleasing?? Stryd featured this aspect in their marketing in an effort to come up with reasons to upgrade!
Yeah he was in a leading group of 3 that flew past me when they must have been in their last mile and ended up 2nd overall. Looking at his Power of 10 got to assume has had a few comebacks but basically is running as well now time wise as an M50 as we both were in 2005 and back in 1993 he won the BUSF XC and was 10th in the NCAA D1 XC which is a whole way higher level of course. As for the Stryd, it is "handy" that the newer one has a slightly different clip and a bit more orange on the Stryd itself so can remind myself which one is which. Otherwise be hard to know which is which other than, for now, my new one being a bit cleaner and newer looking!
@@TimGrose basically Simon is now a better athlete than he was when younger. He is genuinely world class as an M50. I look at his times and can only dream of getting anywhere near them.
@@josephgonzalez_ yeah perhaps a topic in its own right. I think the landscape will continue to evolve if the likes of Bekele "hangs around" for another 10 years! At the moment there isn't really any "point" in pro runners continuing too much past early 40s as the performances will inevitably start to decline and you don't earn anything with a good age graded score :)
@@TimGrose haha true. The M50 scene might indeed look very different if Kipchoge or Bekele decided to continue. With plenty in the bank, a lifetime of punishing 120 mile weeks and nothing to prove, they’ll probably not bother.
i've been waiting for review of this. what i want to know is the consistency of distance measurement with different shoes and how fast it picks up change of pace
I will try and dig into that. TBH I have never really found a need outdoors to take distance and/or pace from the Stryd as where I normally run, GPS based distance and pace works well and even more so with Multi Band GPS. It does also take away those thoughts of does different shoes, slightly different Stryd placement positions, your pace, the terrain impact things when all a calibration factor is is a simple scaling of the raw pace/distance it detects. Are you running in locations and/or with older GPS devices that you feel that the Stryd for pace/distance is "needed" ?
I am impressed by the Running Stress Balance. Twice I felt like I pushed it to much like Tempo 8k in the morning and 6K threshold in the the afternoon (usually I do easy run and hard effort per day) next morning Stryd said OVERREACHING - 42. Garmin never gets it right 🙄
I will need get a good set of runs back into the Stryd Data Center as only my last 5 since got the new one. Have you got the new one as well? That said it is saying "You are training heavily. Be cautious of increasing your running stress." I did this race on Sunday, hour runs Mon & Tue and yesterday 10 miles including 10 x 3 mins, 1 min. My Garmin typically tells me to have a rest day :) Maybe I push too hard although I don't feel I do.
@@TimGrose Yes I have the new Styd. The message before was "you are training heavily be careful" now it moved to OVERREACHING. Beyond advice for sustained training.
Here is the info from Stryd official blog: ---- [Track Your Lower Body Stress, Dial in Your Recovery, and Sustain Your Performance] With the next gen Stryd, we are introducing a new feature to track lower body stress that will help you to dial in your recovery and sustain peak running performance. Driven by Stryd’s new ability to accurately track Impact Loading Rate, it will allow runners to quickly identify and work to recover from large changes in lower body stress that could otherwise be problematic. Impact Loading Rate captures how quickly your body is absorbing force when your foot comes in contact with the ground. Optimize recovery by learning how to manage situations that subject the body to high Impact Loading Rate such as downhill running and running at high speeds. Training momentum is critical when in pursuit of your goals. These new impact data can allow us to offer insights to help you to minimize mechanical stress while maximizing metabolic and race-specific training. We hope this metric will keep you at the top of your game.
Ah thanks. I will have to see how that metric pans out. I noticed both weren't too far apart doing 8 miles easy yesterday or 10 miles very hard in my race here. Both similar duration. Something like 64 and 73. Logically the easy run should have a lot lower figure although I was obviously quite tired yesterday.
Got my first run today with the new Stryd. Be interesting to see if it’s any more accurate for me as I had to have a 104.6 calibration set on the old one.
please update us with the distance measurement between different shoes. also how long does it get to zero when you stop suddenly to see how fast it reacts to changes in pace. those two metrics are what is important to me and my wind pod is a disappointment. 30m/km difference between my lowest and highest stack shoes and 4 secs to react to pace changes - might as well use watch alone.
To be fair with a calibration factor applied, a Stryd is normally fairly consistent run to run although, as I mentioned in a reply to gudboyngdisyerto I never really felt a great need to take pace/distance from a Stryd especially now with Multi Band GPS on my Garmin Forerunner 955. This 10 mile certified course came up more or less exactly that with distance from GPS in this race. The previous day I took out 3 GPS watches and they measured 4.44, 4.44 & 4.45 miles so clearly Stryd cannot do any better than that, only worse
@@TimGrose I've just completed the first run, and had the old pod on the right foot, and the new one on my left. New pod with 100.00 calibration recorded 7.78KM, and the old one recorded 7.27KM.
@@TimGrose Yep, I've been using GPS as the source almost the whole time I was using the Stryd Wind. The new one almost matches up exactly with that GPS would be on the 955 with multi-band. Pulling the GPS data only gets me 7.74KM
I' m not a cyclist so power in Running seems like a difficult concept to get my head around. Also not really seeing the benefit to these metrics tbh. I think for me I' m better off just training by pace or perceived effort. Generally I think it is always a good idea to have a look at what the pros are doing and are any of them training with power meters? Not really from what I can see...
I think one way to look at is a variant of GAP pace but using a different numbering scheme. So really any metric that measures your effort and is independent of the conditions - be that gradients or wind. One would like to add surface but you can't with anything am aware of so got assume a "firm" surface. Then there is the usual story of that metric being sufficiently smoothed so you can don't see a "random" number every time you look at your watch. So the concept is good but even having had a Stryd for about 5 years now I am still like you and mostly glance at pace and the body effectively tells you what your RPE is. On the other hand, I "like" numbers and a Stryd (or similar) provides lots more to ponder on.
@@robin29991 Seville. Same one as I did in 2020 just before lockdown. Sub 3 always the obvious aim. Will have to see how realistic that is in a month or so and decide what to do. BTW there has been a picture of Kipchoge using a Stryd and he seemed to have been using the Runscribe foot pods at some point. But yeah not too many "obvious" pro users who want to "endorse" it.
@@TimGrose Ah, interesting about Kipchoge. Maybe will reconsider now, haha. Good luck with the training then. Maybe you will even race in the Next % 3 then:)
I've never had good AP readings with the Vaporflys or Alphaflys, even when positioning the footpod straight on with a zip tie... I, however, get good AP readings with the wind footpod from Stryd on normal shoes.
Last 3 days, I have tried Endorphin Speed 2 RUNSHIELD, Vaporfly NEXT% v1 and today Pegasus 39 Shield and air power averages for the new Next Gen and old Wind one pretty much same each run. New one 4%, old 1%. That said I have had the occasional "success" with the Stryd Wind but never often enough to give it any credibility. Good that you seemed to have a bit better success with it.
@@sylvainbauge With the older Stryd Wind I presume? I think that is "normal" for that device but having used Next Gen 4 times now and seen 4% Air Power at that rough pace then looks like that is what they now believe is correct.
