This video helped a lot. Mainly bought the Stryd to finally get correct data when running through the first I run through daily. But I have to correct you on cycling pm. Cycling PM work a bit differently and they can very well tell and even teach you efficiency because that’s what they are built for.
Excellent explanation of STRYD power, the best I've seen so far. I've been using it for just over 2 weeks now and you have basically answered every question I had about the STRYD pod.
Thanks so much, that was by far the best explanation of how power in running works, how Stryd works, and how you can apply this in training & planning a race! In short, I know what put on my list for Santa. BTW with my new racing shoes, Nike ZoomFly 3, my stride length increased by 4cm & cadence from 174 to 176. So my pb at the end of a sprint triathlon went from 24:40 to 23:43 (obviously with a year training as well).
I'm working on another video explaining why power is useful and how shoes may affect power. It's looking a the physics of running - so difficult to keep it easy to understand. Hopefully out in about 2 weeks.
@@SwimCycleRunCoach Thanks ! Was out on first run yesterday evening and thoroughly enjoyed it. There was a point where a headwind picked up, so I made a note of the time to check the results later - sure enough, spike appeared in the AirFlow graph. Looking forward to getting the most out of this...
Great video. In my case if I increase cadence from 160 to 180 spm my speed and power also increases. Maybe I have to reduce my stride length, but is difficult to do on the road. Maybe is easier on a treadmill.
It's easier to control on the treadmill but outside you can do shorter distances and will be able to maintain cadence, slowly increasing the distance as you get used to the new cadence.
great video! What are your thougths about the total ground contact when you focus on cadens at 180 (and your normal cadence is 165). I see you get less ground contact per step, but at the same time you get ca. 15 more steps per minute with that lesser ground contact. Will not the total groundcontact for all the steps in you intervall be higher?
Excellent video both in terms of content and presentation. I am reading the Jim Vance book but this video is much easy to get an initial understanding of how power works and its benefits. Hopefully, I can now much fully appreciate the book. Many thanks.
My conclusion of the experiment is that increasing your cadence: - increases LSS - reduces GCT and VO However, it doesn’t make you a more efficient runner: - while pace remains exactly the same, HR slightly increases I would have been impressed by the results if HR would have gone down at the same pace and at the higher cadence, but unfortunately that is not the case. So my conclusion would be to be rather critical when using a power based efficiency metric instead of a HR based efficiency metric: Although the higher cadence seems to lead to a more efficient redistribution of the generated power, it is also considerably more pounding on the body (HR goes up slightly), so ,in the end, it doesn’t make you a more efficient runner but, in fact, even makes you a slightly less efficient runner.
Very interesting look at analysing running power data. (I need to improve my leg spring stiffness. Never seems to be high. Fastest of a recent set of intervals had pace 3:34/km, cadence 197 and still crappy 12.0 kN/m LSS!)
It’s probably best to film yourself and see where your form might be deficient. Get me some video and if it’s good enough quality I could analyse on the channel
Hi. I just bought the stryd power meter yesterday. Today i wanna get as many information about it as possible. I just got to say I really enjoyed your video. It was also very understandable for non native english speakers. I´d like to see more about running with power.
I have a new Stryd and want to do my runs according to Power. But I can only get the current Power metric on my Garmin 255 watch and it varies quite a bit during running, how should (and can I) use it that way?
Hi, I'm in the middle of reading Jim Vance's Run With Power and I ordered a styrd pod. Styrd seems to be using critical power (CP) as the main indicator of performance and they use CP to build training plan, race result estimation and running intensities. This is different than what Vance suggests. I'd rather use normalized power to calculate intensity factor (IF), rFTPw, EI@rFTPw and such. Is that possible (and easy) to extract from the styrd pod data? Thank you
I’ve been running thousands of miles every year for decades and I didn’t know anything about this math and physics. That’s probably why I enjoyed every single run I did.
Being a slave to the numbers would become very numbing. However, they can be a useful tool if you're of a mind to use the data. It largely depends on the type of person you are and what you want from your running. Enjoying your running is probably the best motivator you can have.
Great video. I have been running with Stryd for a few weeks now. In the past I have used 1km splits to judge my pace. I have not started using power during my runs but would like to start. How is the best way to use it on my Garmin to judge pace? average over 1km? 3s average?
Very good explanations. Tempted to get a Stryd after this as it makes it all understandable. One question, i have a Garmin Fenix 6 which when you choose a route it can also work out the pace to hold at any given point during the race taking into accounts hills etc plus you can also skew it by telling it that you want to do a negative split or push extra uphill or less etc. Would that work alongside power? so instead of a pace you get a power to hold which varies depending on you go uphill or down hill etc? So instead of a "pace pro" it's a "power pro" - does that question make sense?
The Stryd isn't programmable if that's what you're asking. You would have to adjust your power output based on the numbers it gives you, much like pace. However, I wonder if you could download a Workout to run as you do the race??? Haven't tried.
No! Bear in mind Stryd is a RUNNING power meter. :) If you meant indoor (treadmill) running, the answer is "yes" (slopes need to be dealt with manually).
The Video is amazing but I do not think Stryd is accurate. In my experience Stryd is a different way to consider your training but not necessarily the answer for a a better PACE - Distance reading. It means you will get a tool to improve but not a device to be sure about what you are really capable of in a competition.
I was very excited when the stride first came out. But then I noticed that the Stryders do not address running efficiency and technique before they get into power. Inefficiency is a waste of power - which is what we measure if we do not first address poor technique.
You should be able to address the negative factors in running through the metrics such as GCT, LSS, Cadence and Vertical Oscillation. The whole aim would be to see where you are losing efficiency and power. Perhaps I should do a video on those topics though?
I believe many Stryd users monitor and try to reduce their form power. This is essentially the same as monitoring and trying to increase efficiency. I am not aware of any other way to quantify efficiency as well. Some of the other sophisticated quantities appear to be useful to help find how to reduce form power.
@@liamroche1473 A couple of years back I went through the data on the stryd site, and they have race times with pace by age. All the 16-18 yo racerswho were winning had cadence avg 220 and the average older runners who were winning were back down by 180. A quick check of race pace 100m to mile at the Olympics shows that Olympic winners in the 100 to mile have cadence of 250ish. So for me I am mostly interested in records medals scholarships etc. So 250. I would like to see videos about using stryd at Olympic winning levels. Thx for the comment. Maybe I should find out more about the stryd raw data. Is that still available? cheers
