I read a NIH study that showed genetics accounted for 47% of subjects’ increases in VO2max while following a HIIT oriented programme. So genetics may also play a role in fatigue resistance as well. Were this to be true (there’s no evidence this is the case atm), then genetics provides an edge. Another factor not addressed is psychological. People react to exertion differently. Some fold, some dig in. Most of us fall between these two extremes, though I suspect repetitive training and competition by athletes likely conditions them to tolerate adverse physical demands as a matter of course. The other issue briefly touched on in the video is exercise economy. This might be better described as kinematics. We’ve all seen flagging runners whose limbs are all over the place, cyclists whose joint pain persists in the absence of a diagnosed medical issue, etc. Good control of body movement has a few different components but it undoubtedly leads to more efficient locomotion. That efficiency endows an athlete with greater endurance simply on an energy basis.
@gcn yep, she is going West to East. By the time she has rolled down into the Southern hemisphere, the furious 50s and roaring 40s winds will kick in and they blow West to East. See, cheating!
C'mon, Dan and Si, don't let us down, what tires and gearing were the beach cruiser guys running at Unbound? It looks like they cracked the code, should've been the topic of the week. 😀
@@gcn Yes, GCN, this is your moment to shine as investigative cycling journalists, find out everything for us, tires and gears and pressure and as another viewer is wondering, chain waxing. Who knew, half a century after the NorCal downhill scene, klunkers would roll in formation to the finish at Unbound like Ford GT-40s at Le Mans in '66. 😀
As a retired driver of very large trucks and long time cyclist I see the probs from both sides, the worst offenders in trucks are mostly the younger newly test past drivers who do not seem to be aware of every thing around them concentrating on getting the job done (to many deliveries in many cases) in the case of the cyclist the about town rider ie going to work/ shops etc they seen to think the trucks just should not be on their roads now the lycra lads they really do own the road, when driving a large truck you really do need eyes every were because most of these guys are either looking at their head unit or trying to be as aero as possible, were I live there is a rather straight 2km very busy road with a parallel shared cycle/ walking route 3.5km will the lycra lads / girls use it not a chance it gives me the gitters just watching them even just driving a car past them.
there is a correct way to do all of those movements and you are supposed to go through the full range of motion . if his bulk is impeading his range of motion then that should have been stated before the start .
Colorado has some pretty sweet ebike tax credits that are attracting people to try it. City festivals are also offering secure bike valet to cut down on parking and encourage bike usage.
I can't even comprehend being able to do 200+ miles a day for multiple days! 🤯I've been road cycling for 10 years and can count on one hand the number of times I've ridden over 100 mi!
I don't believe fatigue resistance is a totally new concept, Dr. Stephen Seiler has been talking about this for a few years now, but he uses the term "durability".
I'm a cyclist and a HGV driver. I have driven acorss europe. I've honestly never had an issue as a cyclist with a hgv, prob because I just stay back off them at junctions and traffic lights. A HGV driver has so many blind spots I take it upon myself to make sure I am visible to the driver by staying in his mirrors or making absolutely sure they know where I am. Granted not always easy and may mean laying up behind a truck but I feel it is safer. When driving, If I do see a cyclist I do my upmost to be considerate but honestly. It is so hard to keep track of cyclists around the lorry in towns and city's. As for victim blaming. Truckers do carry more of the burden when it comes to protecting those around them as they are considered professionals and usually held to a higher standard. But greater understanding across all road users is whats needed. Cycling is safer on the continent maybe due to better cycle provision but definitely a greater awareness and respect over there as well.
I hear this all the time and all I can think is why we allow vehicles to have so many blind spots and then allow them on the roads unsupervised? Let’s take the largest most dangerous vehicles and not allow the driver to be able to see - makes so much sense 🤦♂️
Better training of cyclists would help. It seems to me, cyclists killed by hgv are often inexperienced and women - won't be popular point but I expect on *average* women are more likely to be less confident getting themselves out of tricky situations and more likely to follow "rules" into a sticky situation (eg if you're happy jumping on to the curb it can make you safer) Note, I do believe some feminists made a similar point framed as roads not being designed for women
As a regular bike commuter, i never cease to be amazed by the ludicrously dangerous positions some cyclists put themselves in. I'm also a member of the Institute of Advanced Motorists - much of the training to pass the IAM test is observation and hazard awareness. All traffic users have blind spots - most cyclists don't have mirrors, we all need to take responsibility for avoiding conflict situations on the road by being more aware of the limitations and constraints of every type of road user.
@@peterholmes1307 not having mirrors isn't equivalent to a blind spot. you don't need mirrors to be aware of what's happening around you on a bike... funny thing, I rarely see anything ludicrously dangerous by drivers or cyclists. But some people see this stuff all the time. Mainly people who don't do one or other, or people who have been on courses... these people should ask, if this is ludicrously dangerous, how come there are so few accidents?? agree about all parties taking responsibility though
I've always thought it would be fantastic to see one of the ex-pro presenters go back to training full time to see what they can do or still accomplish now with years added to the body. You have my vote!
@@feedbackzaloop good recommendation, Phil makes fun content, and jfc can that man climb on a bike! His clip where he crashes due to the solid finish line tape is hilarious 😄
@@gcn well they were all distinctly average when they were pro, and I for one think they could get close to that again if they really gave it their all
On the bus driver thing... When you live in a surfing town like San Diego, everybody surfs. Your dentist, your bus driver, your teacher, your friend's grandmother even. But in a non-suring town like Dallas, TX, if you mention you're a surfer, everybody immediately starts making fun of you with, "duuuuuuuude... surrrrrrfs up brrrruuuuuhhh." like only people with brain damage surf. Goes to show that if you don't do something or know people who do, then your perception of that activity can be really poor.
I used to investigate Fatal Road Collisons (no such thing as an accident) I dealt with 40 odd deaths in 2yrs. Nearly all the cyclists deaths I dealt with had gone up the inside of lorries or buses who turned over them at junctions.
There should be videos made on the likely causes of death on a bike. Like if it's most of the time because you're caught on the inside of a large vehicle, then cyclists should know.
Most motorists would know better than to go up the inside of a bus or lorrie, so why shouldn’t cyclists? It isn’t victim blaming to put the onus on the cyclists, it’s common sense given the visibility limitations of the bus/truck driver, and the lack of protection for the cyclist.
Well, we force cyclist to ride on the side of the road (due to usual locaties of a bike paths or just for staying "out of the way". But when vehicles are making a turn, crossing this path, they should not drive there? Seems odd. Also keep in mind when cycling it is sometimes difficult to predict which vehicle is going to turn, especially if they approach you from behind with (much) greater speed. When riding a bike, of course you should be aware of your surroundings and carefull around large vehicle. But i think most people are (it is very scary, just try it out).
@danielakerman8241 totally agree, but I didn't think the original initiative was putting the onus on the cyclist, just an awareness of what the driver can see. I'm cautious in my car when I know I'm in another driver's blind spot. There's too much emphasis on things being someone else's responsibility without taking personal responsibility or risk awareness. I'm getting a little bored of GCN consistently seeking out cycling victimhood. We're all sharing the road. Seeing others' perspective helps.
Well as a cyclist for about 40 years and a member of the general public I've witnessed several serious vehicle collisions with cyclists - none of which involved cyclists going up the side of buses or HGVs - so I don't think your 2 years are necessarily that typical.
Shouldn't all driver training include cyclist and pedestrian awareness as part of hierarchy of safety regulations which also need to be enforced. This could be how to achieve the understanding of the relationship between different road users as in the Netherlands with the safety implications of this.
There was no grass around (I live in Tokyo, it's super urban for hundreds of km) and in a tropical country I would avoid due to the amount of insects that could be lurking 😨
for rim brakes yes - for hydraulic brakes no. shimano state this on their documentation - "When turning the bicycle upside down or on its side, the brake system may have some air bubbles inside the reservoir tank which are still there when the bleed screw is closed, or which accumulate in various parts of the brake system when it is used for long periods. This disc brake system is not designed to work with the bicycle upside down. If the bicycle is turned upside down or on its side, the air bubbles inside the reservoir tank may move in the direction of the calipers. If the bicycle is ridden in this condition, there is danger that the brakes may not operate and a serious accident may occur. If the bicycle has been turned upside down or on its side, be sure to operate the brake lever a few times to check that the brakes operate normally before riding the bicycle..."
Here in Australia, articulated trucks and busses usually (always?) have two big signs on the back -- one pointing out that 'do not overtake' when they are turning (because of 'pinch' in the articulation) and the other, on all heavy vehicles, a simple sign that says "if you can't see my mirrors i can't see you".
When I started running in December I wore cycling jerseys. Three pockets on the back to carry phone, food and keys. My running club all know me as the cycling guy.
My point of view to drivers is,, if that was your son, daughter, nephew, sister ... on the bike How much room would you give them ,,it always makes them lost for words,,
I think Dan has a bee in his bonnet over Surron type bikes. They aren’t e-bikes and are in fact, by definition motorcycles. As are most food delivery bikes seen razzing around city centres.
THANK YOU GCN for putting in the beach cruisers at Unbound! It was inspiring! I own one of those single speed cruiser brake Walmart brand beach cruisers, but I have gravel bike handlebars on it.
@@JonCanningsStay awesome Jon. I still watch your Kierin bicycle track racing video you shot in Japan. We watch the racing often and enjoy it on RU-vid.
@@gcn Sorely tempted! I have thought about it a lot. The costs would be about $2K for transportation, food, hotel, and support team, and I can't get free time off from our farm during the June planting season. However, I can pedal the local rocky canal trail and daydream of Unbound for free.
I would never go out without my phone. Firstly, because I use it for music, but my wife also insists it's a safety issue. It didn't use to be any kind of an issue before, but now I got a massive phone which won't fit into most athletic gear pockets easily. But I have some running belts I use now to carry it.
Yes, I agree. $1800 is a lot of money, but Bont have been doing full custom shoes for years. If you have any foot issues that affect your ability to ride eg. Every bone in your foot has been broken well fitting shoes are a non negotiable and the $1800 becomes irrelevant.
In the segment about HGV drivers and cyclists, Simon mentioned victim blaming. He's spot on with this observation and it connects to the last GCN Show I watched in which Simon made an analogy with feminism. In the same way that women are vulnerable on the street, cyclist are the vulnerable road users. Victim blaming, street harassment, rape culture and so on all have their parallels with cyclist's safety on the roads. My point is, a lot of what we need to know about how to effectively campaign for cyclist's safety on the roads is already there in the history of feminism.
Short side note on Lael‘s record attempt: I can highly recommend the podcast episode of „Life in the peloton“ by Mitch Docker with her. She is the most badass person I have ever heard about.
Eagerly awaiting the next installment of Dan's journey back to health & fitness series. Is that still happening? I'm on the same journey, minus the "back"
Cyclist' Safety: In California, a driver needs just one word to avoid any responsibility for hitting a cyclist, "Whoops!" Well, okay then, off you go. Thanks for stopping. Enjoy your day.
Chuffed to bits that I finally got a comment worth mentioning! I often think that finding out who's 'fault' somethng is almost never addresses the real 'why'. As a cyclist driving a bus I find myself instinctively looking the the gear and stance someone is riding in. And that usually gives me enough information as to whether or not that rider is likely to ride out of the saddle soon (and sway more) or slow. Eg: hard gear approaching an incline. Some colleagues get randomly surprised that they'll see one or two riders, overtake them without thinking much more about it, then are surprised to suddenly get swarmed by loads at the next set of lights. But to me, if I've seen a few riders in a similar kit, I'm expecting them to be part of a larger group and I'll spend a short while expecting them around me. I'll also hug my bus along the kerb. I don't give anyone the choice of pulling up along side me on my nearside. I could list a thousand things but here's a few from a bus driver`s perspective that I've never seen mentioned on posters: When two or more buses of the same route are running together, it usually means that at least one of them is late. That driver might be glancing at the mirrors instead of looking. There is a difference. Doesn't matter how bright your bike light is. If you're in front of another vehicle at night with its headlights on; you are invisible. Some bus mirrors wobble to such a degree that drivers can only go by shapes large enough not to get blurred out. Cyclists are not large enough. On a narrow road with a bike lane. Buses can't avoid entering the cycle lane. Especially on a curve. Sorry about the long waffle. I'm usually on one of these: 55, 56, 165, 215, 256, 257, 275, 365, 496, 499. You're all welcome aboard (folding bike only. No electrics.)! 🙂
I have a nautical dictionary that defines a "Figurehead" as a "Decorative dummy found on sailboats". Arguably Si and Dan don't need an additional one on their bikes.
I normally cycle in france, but last year I went on a ride in England and I had so many close calls. And I do believe that England needs to improve the awareness of both the riders and vehicles and the infrastructure for cyclists.
Most definitely my endurance has improved over the years, but I cannot go as hard for as long in training as I used to. I recognize that I am getting older and slower, but in some ways I'm a lot smarter, enjoying the ride a lot more.
Interesting comment on fatigue resistance. On rides less than 100kms my friends destroy me but when the distance starts adding up, especially above 150kms I start to come into my own even though I am not going any faster.
Ooo that is interesting! Alex found something very similar when he went on a long ride with Ollie 👉 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wMFthWMOBEo.html - He could probably take Ollie in a Crit but over long rides Ollie has the edge

Ryan with the ‘worst bodge ever’ here. #1 it is actually my coworkers bike. #2 the MTB shifter is mounted on his 1x CX racing rig, not his MTB. He takes the shifter and derailleur from his MTB and mounts to his CX as he only does a handful of gravel races.
US teens picking e-bikes? Not too surprising really; good, small, starter cars are in incredibly short supply due to the combination of high US crash rates and car manufacturers refusing to meet market demand for them; and bikes have improved out of all recognition in the last 15 years, not just due to ebikes but also due to improvements in brakes, wheels, tires and so on. Note that the US category III ebikes that do up to 28 mph (45kph) do require pedaling; however, quite a number of people have made, shall we say, modifications to allow faster throttle control than the 20mph (32kph) throttle-capable category II bikes are capable of, and it's this subgroup that gets flat out scary on bike trails and really do not belong there. Then there are also electric motorbikes that make no pretense of pedaling whatsoever.
Thanks for the show. Entertaining as always! Caption Contest Attempt 1: This helmet is ridiculous with that ferring on the back! Yeah but at least I'm not wearing 3D printed shoes
Have you seen the cost of driving lessons, insurance and small cars in this country [UK] it’s no wonder kids are not learning. My daughter’s lessons cost a fortune 😢😢😢! I could have bought a Specialized SL 8 instead to date 😮
These Lore shoes look ugly and indeed impossible to clean, HOWEVER there's a very interesting cam Nichols video on them. Very expensive, but for good reason, and they could legit be a tangible performance boost. You should have a closer look, even for their multi axis carbon 3d printing robot alone, it looks like they are printing Aliens.
I don’t understand why fatigue resistance should be labeled as the « 4th dimension of performance » … after all isn’t « fatigue resistance » just another way of saying « endurance » ? That’s the one dimension that rules all the others, and in some sense the only dimension there is to cycling, from a 1h crit to a 6h classic. It’s all good to dump a 7w/kg effort in the first 15mins, but it does not determine outcome as much as 7w/kg effort in the last 15mins.
E-bikes are not the same as throttle bikes. E bikes require pedaling, or “pedal assist”- while e-motorcycles (no pedaling required) have a throttle. This confusion is what keeps e-bikes from being accepted on trails
I would imagine fatigue resistance is mainly down to training. Riders like MDVP have a high fatigue resistance for anaerobic efforts, whilst riders like Vingegaard would have a high fatigue resistance for long aerobic efforts.
what kind of attention was paid in the fatigue-resistance studies to amount/quality of recovery? Aside from any different inherent physiological advantages, pro athletes are usually not working a full time job; amateurs don't usually have that flexibility. I can't imagine that there isn't at least some positive aggregate effect of higher-quality rest (presumably a priority for pros) just as there's a negative aggregate effect from poor-quality rest. How close could a good amateur come to a pro on other metrics if, say, they were given all the tools/space/work coverage to get a good night's sleep every night for a week?
It’s quite easy, but in this company, controversial but when I’m cycling I don’t go up the inside of vehicles at junctions / traffic lights. Regardless of the layout of the road. I’ve always done this and therefore never had a problem in this scenario. It’s not rocket science.
As a former truckdriver and a cyclist, I can say it can be a nightmare, driving in the city with cyclist. When a young kid on his bike, musik in the ear and locking at his phone, drive right out in front of you.... my heart stopped for a few seconds, but Lucky for him, I saw him and wasn`t in speed, because its not easy to stop 57 tons in a second...... We do our very best and have eyes everywhere. But please stay behind the truck at a traffic lights and wait for it to turn, before you continue and we all come home safely :)
Regarding fatigue resistance: it's probably both genetic and trained. Like with other physiological performance parameters there are some people with extremely high numbers, quite a lot with very good numbers and most with around and under average preconditions. I guess if you mapped it, you would get sort of a bell curve of probability distribution. That's also essentially what the outcome of the study done by James Spragg is suggesting: even among professional cyclists (who do a lot of training) there are significant differences among the 14 participants of the study due to their genetics. On the other hand, if you look at it from an individual perspective, you have and keep the genetics nature has gifted you with, but with training you can unlock your full potential, which doesn't become available if you only sat on your sofa. The reason behind it is the same why training has an effect: your body adapts to what is needed - only if the demand is minimal, the body adapts to a very small part of what it could do theoretically. That is the experience Si is referring to when he pointed out the difference between his pro days and his current abilities in the department of fatigue resistance. Personally my observation is also much improvement with training volume. I did the same event (Vätternrundan 315 km) last year and this year averaging approximately the same speed, power and heart rate numbers, but feeling spent last year in the end versus feeling quite fresh and to be able to go on for much longer this time after 12.000 km of training in between.
Fatigue resistance is endurance, not a dimension of it (not being divorced is marriage, not the fourth dimension of it). Endurance is how much you resist until you fatigue and have to stop. That happens sooner or later depending on intensity (aerobic endurance, anaerobic endurance, etc). Every intensity has its specific limiters (causes of fatigue), which you can overcome by manipulating VO2 max and the other real markers of endurance (aka training).
I found out that my resistance to fatigue is naturally high. I entered a 200 km ice skating race in 2012 in the Netherlands without training, and was able to finish it. Since 2020 I’ve started endurance training and have done multiple 8 hour plus events, I am not necessarily the strongest at the start but I can just keep on going. Same for my sprint, my highest ever wattage for 5 seconds I did at a sign sprint after 9 hours group ride at 32 kph average at 230 watt average. So I am sure you can train it but some people have some of it from the start. Strangely enough I don’t have good multiple day fatigue resistance, but mainly during a single day long race or ride
Ilore shoes 😂😂😂 Pretty sure sticking your feets in à tissue box would render them more aerodynamic, and more interesting to the group ride fellow jokers
Ive got a small fanny pack for my phone while I run. I need it to play my podcast/audiobook and the bag keeps the phone firmly on the small of my back without it wiggling around. I used to carry it but the extra 300g on the end of one arm messes up my form.
The problem with these young guys out in the U.S here using these e bikes to get around is that they ride recklessly all the time. flying by other cyclists, like myself (im 21 btw not just some old fart ranting about young people), and other pedestrians on segregated bike paths at speeds easily above 40mph. Along with the fact that they aren't really getting any real exercise and are just not taking any basic traffic laws into consideration at all. Also, many of these kids don't even have basic bike handling skills on a normal bike, now just imagine a dumb 16-17 year old kid, with dogshit bike handling skills, hoping on an electric bike that can go damn near just as fast as a motorcycle, and having to share a tiny bike path with them, it's a recipe for disaster. I believe in Seal beach, they are banned entirely, and cops often confiscate these kids bikes because they say they need a motorcycle license to operate them, along with them not being able to be registered as vehicles. But hey, I'd rather see them outside fuckin around on e-bikes then being inside all day and not doing anything outside. Here is a video from an interaction between a young man and a seal beach police officer from instagram so you know im not just making stuff up about the ban, etc. instagram.com/reel/C77kX4MSHGm/?igsh=MzRlODBiNWFlZA==
Daniel Lloyd figure head? thats easy his favorit beer label :-) I think they guy with 3d printed figure head miss the classic head badge from the past. Not sure when they got weight saved away, but the Bianchi and Litespeed ones where beautiful
HGV drivers are fine, as professional drivers they cannot afford to risk their livelyhood. By FAR the worst are tractor drivers, I've had to at times literally dive into a hedge to avoid being crushed.
Fatigue resistance at high intensity is all about lactate threshold, surely? Everyone has a point where lactate can no longer be processed efficiently. Mid-distance runners know this well. You can train to increase your lactate threshold (strictly the 'upper lactate threshold' - the lower one is around the top of your 'zone 2') by use of intervals that gradually increase the volume or work at lactate threshold between rests. Every 10k running training plan is built around this.
Honestly Sy, your video are my favorites to watch, mostly because of the content. I think nowadays that is where your quality lies. Getting into 4 months of training to get back to what?
In regards letting other Road users know a cyclists head space I’ve lost count how many times I have been cut up. Rather than shout I now take it upon myself to tap the window if the car parks up and explain “all I want to do is ride my bike and my children want to make sure I come back alive. By you cutting me up etc then that’s not helpful to that and next time could you consider my children” So far most drivers have apologised when explained I wish this would be explained to the like of Clarkson and other petrol heads as it’s about caring for loved ones x
I cycle and drive HGVs and buses as I'm a mechanic. The only thing I can say to people that cycle bikes is you wouldn't under take a turn vehicle if you were driving your own car. Car drivers and cyclists alike do put themselves in bad situations and they don't have the awareness of what is going on around them. Everyone is responsible for their own safety on the roads. Accidents do happen it's sometimes unavoidable but to have the arrogants to think everyone should be watching out for you on the road whether you are on a bike or in a car or HGV is why there are accidents.
