    GCN has been my favorite channel in RUclips when it comes to cycling.. I've started riding and touring and the videos have been very helpful in planning these.. Recently I've done a 100 km ride in about 4 hrs.. Big deal for me coj I only used to cycle to my work place.. Now it has grown to be a passion.. Great work with this video as well.. Cheers.. Keep inspiring for a healthier world through cycling..

    also if Blake has never done an FTP test before, his FTP score could actually rise significantly just by learning how to do the test better, or better pacing

    • @LomTong
      @LomTong 6 лет назад +3

      Chris Capoccia I was thinking the same regarding the intervals.
      Blake hasn't done any training of that fashion before, whereas it's a fair bet that it's Si's bread and butter. A lot of it is about practicing and knowing what that 30 seconds should feel like if you wanna be dead by the end of the third one.
      I reckon ot would have balanced out just fine if Blake had more training experience.

      @mikea6710 3 года назад

      All the points here are, I guess, why ftp doesn't matter as much as we think... Why would you want to cheat for a better ftp? Obviously, if the guy was more conditioned to pro tour fitness, he would do better, but why would you want to have a slick nice prepared ftp vs a pure blind tested ftp rating.. If a liar knew the tricks of passing a lie detector test, and they pass it,.. he is still a liar, right?

    As a hardcore DH mtbker this training stuff seemed pointless...until I did an endurance mtb race and my lungs almost went out through my nose😅I already followed GMBN so I gave this sister channel a try. I don´t regret it at all. You guys give a lot of very interesting nutrition/training tips that can be applied across all cycling disciplines. Just by following these I was able to finish the next endurance mtb race in top shape and even smoked some of the guys that left me behind in the previous one, but, above all, I finished feeling more happier and healthier than ever before. Keep it up guys!!!

    • @MDonovan
      @MDonovan 6 лет назад

      I think most FTP tests are around 20 min or less ; I don't know where the one hour comes from. that value would be 10 to 20% lower and often the VO2 is measured as well so the snorkel and lactate lancet distractions might take off 5 to 10 %. In the big picture you would have to measure consistently (sprint first then FTP) over standard intervals to have an idea if the training regimen is effective. hard to do if you are an actual racer on the road. But for everyone else, sure book an FTP and VO2 max test , maybe summer and spring, you'll have a great time.

    • @ow916
      @ow916 6 лет назад +2

      @@MDonovan 20 minutes is a common test, because for most (but not all) 95 % of 20 minutes is accurate enough, while also doable in practise. It's a practical solution, not a theoretically optimal one. Lactate measures doesn't impact output at all in my experience. Just a pinprick. The VO2 mask I've used is open, and completely unnoticable when approaching pain zone. Possibly those where you have to bite might impact a little bit, but really, the exertion hurts most regardless. ("Approximately one hour" comes from the definition of FTP, as most athletes can work at threshold for about an hour.)

    I'd put money on Blake having a higher FTP. Those tests take some skill to perform well, knowing how hard to go, ramp up, down or steady are all things you can only learn after doing a good few of them. Also, this will throw the numbers off for the tests after. Si was spent after his FTP because he knows how to put that max 20min effort out, whereas Blake looked tired but definitely not as much as Si so had more in the tank. This would mean Si would have his edge knocked off for the following tests but Blake wouldn't so much. Interesting test but not exactly groundbreaking, a sprinter needs to work on endurance and a climber on their sprint, who knew ;) Saying all that, one of the best GCN vids for a while :)

    • @MDonovan
      @MDonovan 6 лет назад +1

      it is an interesting conundrum who can be a better all rounder...like Sagan vs Martin, Cancellara and Wiggins show the disadvantage a strong sprinter has unless he has the best team to take him to the line, I think Sagan and Gilbert are classic all rounders now they really have to work hard (training) to get the win and age is a factor too

  • @leeshirley14
    @leeshirley14 6 лет назад

    Excellent video! Just completed the TOC at 80% of FTP for the 3:30 to complete the 80 mile course. Nothing left in the tank at the end! Following the numbers really helped by having a strategy to prevent burning all matches too early!

  • @walterzabe4825
    @walterzabe4825 6 лет назад +4

    I have a powermeter because it helps me to keep tracks of my improvements but I don't use FTP as a training value anymore. I use heart rate as runners do to do tempo, sweetspot or threshold sessions (great video of Jack Daniels about threshold).
    The only test I do is the MAP test (maximum aerobic power) every 4weeks block. Starts at 100watts and then increase every 2min 30watts until you colapse. For exemple, mine is 410watts and my maxHR is 182. It is more or less the same as the Vo2max test but from my point of view more accurate. I use this value to do 30"/30" or 1'/1'. But for the 2x20min I stay at 90% of my maxHR and I check my power but I don't target a power number. For swetspot max 85% and tempo 80% of maxHR. I use to training with 20min test value * 0.95 and...very fatigue and not great results cause my FTP was overestimated and thus the workouts were to high in intensity. Since I work with HR for long intervals I have better improvements and less fatigue over time. Your heart rate is the reflexion of your fatigue. Your HR is more accurate to reflect your current threshold. In my opinion the FTP value is not useful at all and its calculation 0.95 of max 20min test is not accurate. Just ride at max 88% or 90% of maxHR and you'll feel your threshold. Do what runners do and transpose it to cycling. I do gandfondos and train like a marathonian. If you do crits train like a half marathonian or a 10km runner. Less time and better results. 4X4weeks blocks before your primary event of the year. Mine is the 8 july for "L'étape du tour" I feel great and building my fitness without fatigue.

    Great stuff, thank you to Si, Louis, Blake and production team. Looks like it was filmed in some kind of Russian Gulag 😂. Thanks Blake for coming over to the dark side and participating. What I found most interesting is that Blake could be in such fine form for sprinting and very acceptable FTP and yet he had never tested before. Therefore he just arrived at this point from riding his bike and doing what he loves to do, cycling. I'm a great one for numbers and love the scientific approach, but I think this demonstrates that you should just get on your bike and ride it, regardless. Enjoy cycling! I raced an 80km mountain bike race yesterday with 1900m of vertical ascent and decided to switch power off, simply concentrating on cadence between 70-80rpm climbing and as close to 90rpm everywhere else. I just drove the biggest gear I could whilst maintaining that cadence. I don't think I could have done any better riding to power, I just went as hard as I could, all the time (heavily supplemented by SIS 😂). 37C at one point, I can confirm that their isotonic drink works! Ride on, Tim

Run it like a stage race - a road crit, a dirt crit, a road race an XCO race, a road climb tt a dirt climb tt and then a road downhill and a mtb downhill. What do you think GCN GMBN?

    • @joshuafoster8976
      @joshuafoster8976 6 лет назад +2

      Flat road,so si pushing 350watts Blake is drafting (30% saving) both at FTP. So it's kind of even. But if si went long he wins. If si accelerated out of corners 550vs500 he's won. If any sort of hill is involved Blake's weight+ weight of pecks/power Vs si's skinny frame/power si wins. Descent or sprint money's on Blake.

    At the beginning of 2018, i switched from TrainerRoad to Sufferfest and immediately had to take one of their 4DP tests. I trained for six months using these 4 new numbers for my targets and noticed a massive increase. I went to a race in May and knocked hours of my previous times. The benefit of having a 4DP profile is that workout targets then become much more precise and useful. How about doing a review on Sufferfest and the people behind it?

    Great video!
    My thoughts are that in order to win a race, you have to be able to finish a race. The ability to sprint isn't going to help me much if I can't stay with the pack or if I'm just too tired at the end of the race to put in that effort needed for a sprint. Targeted FTP training has really helped me and I find it to be a great tool.
    My week is a combination of HIIT (usually by chasing some local segments), SST (most often done on my trainer using erg mode), an easy endurance ride (the long Sunday ride where I can relax and enjoy the scenery and reap the benefits gained from the harder mid-week sessions), and rest. Then sticking in that tough FTP test about every 6 weeks just to make sure I'm on the right track.

    The Sufferfest do a really great job of this sort of testing. The 'Full Frontal' test (5s, 5m, 20m, 1m) will identify your rider type and then match you to a training plan that addresses the cycling weaknesses that the test exposed. It would be a great GCN video to do the testing and then follow a few workouts - we love the suffering :)

    I come from a running background. There are some fascinating studies done comparing aerobic and anaerobic contribution to races of varying lengths. And once you get beyond 100 meters in distance, the "fuel" for every race is primarily aerobic. Obviously, the greater the distance, the greater the percentage of aerobic contribution.
    But the idea is that, even for a 200M runner, aerobic ability is important, and probably the main differentiating factor between runners. This is true even though this is through of by many as a primarily non-aerobic event. By the time you get to 400M, it's almost all aerobic, with very little anaerobic contribution. The take away for me...is that, in running (and cycling), lactate threshold (FTP) is an important and relevant number and a very relevant estimate of fitness for all athletes -- and a good measure to structure training around. But, perhaps, at the margins, the anaerobic contributions can be a difference maker in races, provided that the anaerobic training doesn't sabotage the foundational development of aerobic capacity.

    These analyses closely resemble The Sufferfest 4DP power profile with five second neuromuscular power, one minute anaerobic capacity, five minute maximal aerobic power and 20 minute FTP. Sufferfest stopped using a standard 20 minute FTP test last year for the same reasons that Si illustrated, that it doesn't adequately reflect a rider's strengths and weaknesses.

      @jaykan1002 6 лет назад +7

      Just a bit of discussion I suppose.
      Interestingly, there are data out there stating that the NP of Michael Valgren during an entire tour de france stage is ~259w & 3.64wpk. Keep in mind that's over the course of ~6 hours and he's not a GC rider, so he actually have to work harder to pull for the leader. Factoring in that NP is usually higher than average power used to calculate FTP, I'm thinking it might be possible that one can have the ball park of ~260ftp and/or 3.64wpk would be able to sit in the peloton???
      Now of course.... there will be a section of the race where the speed and intensity might rise significantly.... some of that is already factored into the NP, but one would probably still need to have the wheel to hold the wheel in order to stay in the draft for the whole race.

    #GCN what I’m taking away from this video is that I need solid endurance (ftp) but also need to identify my strengths and develop them. I have found a great 3 minute 11% grade climb that I lap over about 4 times. It’s increased my recovery time and all segments are getting faster. Based on this video I feel I’m trading properly. Thank you!

    So plans are for 50%...
    Thanks so much for all the input and motivation.

    Great video! Blake and my numbers are VERY similar (fast twitch guy with pecks here), but I only weigh 65 kg and am 40 years old. This exactly explains why training sessions this winter based on FTP on Zwift were so variable. The intervals (the 30 sec bit at the end) were always relatively easy but the longer sustained efforts were harder. I think it’s time next winter to do the 4DP on Sufferfest and other “smarter” training software and leave Zwift for my endurance and fun rides.

    Lactate threshold would be better than FTP at setting a benchmark for your training in edurance sports. But it's hard to do a Lactate test (minimal lab requirements). The FTP test is real simple to do and you can repeat at any time - so this is why most of us use it - and with the right adaptations it can help you set that benchmark just as well.
    Now:
    With the max sprint power (around 6'') you get the start point of your power curve;
    I also like the 30'' max and the 4' max. Those will give you an even better knowledge of your body's response.
    With these points (max, 30'', 4', 20', and ftp - the 95% of the 20') you can draw your power curve to some accuracy.
    Then you'll know what sort of training you should be doing for your primal objective (and this is where the fun starts and training theory gets crazy).

  • @ChasingChinster
    @ChasingChinster 6 лет назад

    I do a little heart rate based training, but mostly perceived exertion (RPE) and this seemed fairly obvious to me. FTP is a great data point to know what power you can sustain for an hour, but so many rides fall into times and efforts that aren't "sustain for one hour" like gran fondos and sprints/shorter time trials. Blake and Dr. Louis Passfield were FANTASTIC guests to have on this episode and this is was a high quality video. Thanks, GCN!

    Great video once again with Dr Passfield. Very reassuring that not all training for each rider has to be the same and also very reassuring that each riders physiology is different and so what you can do in training and what you may need to work on is also very different. I guess that it means that we don't have to worry about just one number any more as we are all kind of complex and looking at the issue of getting the best out of us as an individual is also a more complex issue and it would appear that the more the reasearch is done on things then the more cloudy the picture is but also how it does give more variety for riders. Which is good, the thing which seems to come across is not so much to worry about numbers and power but more worry about what you would like to be do, such as sprints or climbs or long powerful efforts (such as a TT) and then try and tailor your training to replicate the sort of effort that you would experience in this sort of situation so that you body can adapt and be able to cope with these sorts of situations. Does seems like a case very much of listening to your body when your training and finding what you can cope with and how you improve things. Really love having more of Dr Passfield on the show and its always really interesting to hear what he is up to and the research there doing. Oh boy Si that was one sufferfest that you had going on there with the testing... such an inviting place to suffer... in the basement👻!! Cheers guys and keep the great videos coming!

    Is Si's greater 30sec interval power likely due to higher lactate threshold that comes with varied types of endurance training?

    • @liverpoolguy79
      @liverpoolguy79 6 лет назад

      Well if we speculate that Si produce aerobically 350w and Blake 250w that would mean that Si produce anaerobically 200w and blake 250w during the 30sec efforts. This would be logical as blakes maximal power is bigger than si´s.

    If this was a 45 minute race between Blake and Simon, and Simon puts 300 Watts for the 45 minutes and Blake puts 200 Watts for 45 minutes, at the final lap Simon would be so far ahead that Blake sprint power would not make a difference. Consistent power is what we cycles should be training for, is good to have a decent sprinting power, but if you don’t have enough to keep up during the race then what’s the point really

    • @morosis82
      @morosis82 5 лет назад +2

      Depends - with the decreased required effort from drafting, it might work out in the wash. As a racer you need both, because it's unlikely you'll end up at the finish line alone and so need to be able to out sprint your competition after a long hard ride.

Then Blake would bulldoze Si on the last round without any chance :D

    Like Professor's presentations and find them very practical. Including this one, where practicality means that I don't need a powermeter (except for some cases of turbo-trainer driven curiosity). HR and speed readings suffice for most of us, and riding with the same speed at lower HR than previous season is enjoyable, i.e. how cycling hobby shall be.
