  • Опубликовано: 8 июл 2024
  • Principles of optimization are explained and applied to the problem of determining the characteristics of a climb, riding intensity and position on the bike which are scientifically optimal for an Everesting challenge. Physics, data collection and data science are used together to calculate the optimal strategy for the Data Science Cyclist. But the findings are generally applicable to anyone regardless of their ability. The optimal approach is determined for a variety of Everesting objectives.

    As a physicist who's done an Everesting I found this interesting. Definitely find the steepest manageable climb and do it at sustainable pace. In terms of choice, a very important factor is to choose a climb where the descent is safe and straightforward and your legs won't go cold. I would recommend to avoid descents of more than 8 mins or so. My ideal would be a vertical gain of 250m and a climbing duration of 15-20 mins. Any longer and it gets more difficult to restart after the descent. Much safer to descend a road you get to know well rather than a longer road that you will do fewer reps on. There'll be fewer hazards to learn to avoid and you will lean the descent much quicker. Not sure if it's possible to quantify this though.

    A thing that nearly everyone forgets to mention that everesting is a very rare challenge where searching for a windy place is an advantage. If you can find a climb in that area that mostly has a big tailwind then it makes the challenge hell a lot "easier" even if the descent will be slower due to the headwind.

    Thanks very much for taking the time to do this. I am hoping to complete an Everesting a few months from now and had selected a 10% 4 mile climb near my house. I was planning on getting a very large gear (34-40), staying seated as much as possible, and going as slow as possible (which will probably be about 7 kmh). Glad to hear that science has backed up my strategy. Again, thank you!

    • @junqueirapedro
      @junqueirapedro 5 лет назад

      Philip Rundle I have not decided on the segment yet. The candidates are Yarabee rd or Mt Osmond (Freeway Side). Think the sweet spot is distance around 2km and grade around 7-8%. But after watching this video I may consider go maybe 9%. But I am not sure. I want to take a very scientific approach and have a good plan and preparation. I think in the end Everesting is an endurance ride more than a steep challenge like the Dirty Dozen. So need to be a grade where your heart rate stays at endurance-tempo maximum rate.

    Hi. Great video. There's an interesting new Metric that seems to have come out of the recent Everesting attempts by Pro's (see the latest Phil Gaimon video). The recent Everesting attempts are being done at Altitude which kind of goes against the grain as there is less oxygen. But the belief is that the air resistance going downhill is less which makes Everesting at altitude when your optimising for minimum time. It would be interesting to get your thoughts on this.

    • @datasciencecyclist6239
      @datasciencecyclist6239  4 года назад

      Great point, Phill. Altitude affects air density, which will lead to less aerodynamic resistance particularly when going downhill. If one chooses a low gradient then aerodynamics will be more important going uphill too. But assuming the slope is relatively steep to minimie time, then one will go faster downhill. This needs to be balanced with a possible reduction in power output due to less oxygen uptake, if oxygen intake is a limiter at the chosen altitude. This changes between people; oxygen intake is a limiter for me at altitude. Overall, I would want a warm day at lower to moderate altitude so my oxygen intake will be maximal to maximize my power output as this is more important that the very short time lost in not maximizing descent speed.

    Low cadence might be more power efficient for these point measures, but doesn't factor differential fatigue profiles for slow-twitch vs fast-twice muscle fibres.
    As for this remark: "There is no good reason to attempt Everesting on a shallow gradient". There sure is: it's harder, more impressive, and more likely to remain a unique achievement for longer. I did mine on a 30km climb and five years later, I'm still the only king of that hill.

  • @TheTheMScope
    @TheTheMScope 4 года назад

    really interesting video...just went a bit beyond my physics knowledge ;-) But just one question concerning the EMG measurements...did you just looked at amplitude or also at the frequency spectrum of the signal. Just intuitively I would rather ride at a slightly higher cadence, so that less "force per contraction" is needed and thus the load can be carried by the more fatigue resistant motor units (which ty my knowledge also are activated with a lower frequency, thus the question about the frequency content)..
    cheers and greetings from switzerland :D

    • @datasciencecyclist6239
      @datasciencecyclist6239  4 года назад +1

      The EMG measurements are highly frequent. They were also strongly correlated with power. You are right that a higher cadence will use more of the aerobic energy system and you can save some of the higher force output per contraction. I agree that higher cadences are better, provided it is naturally comfortable. This can be trained to increase though and will help. Happy cycling and Everesting!

    • @datasciencecyclist6239
      @datasciencecyclist6239  4 года назад

      Thanks for your comment. These curves are calculated using the physics equation included, for different times (t=12 hours, 24 hours) and different gradients calculate the power required to balance the equation; then enter a new gradient and calculate the new power required. This can be done using solving algorithms or adjusting numbers in excel until the balance is right. I wish you the best in your calculations and even more in your Everesting attempt. Even without doing the calculation directly for yourself, the principle which generally applies is that the best approach is usually the climb with the highest manageable gradient for you. Happy riding!

Short & sharp reps seem optimal, as opposed to more drawn-out efforts, it feels like.

Shorter reps mean you get to recover more often, so potentially don't build up lactate or burn energy in the same way as longer, sustained efforts.

      10 metre reps sounds nuts. There'd be a bit of energy being wasted getting going for each rep, as opposed to maintaining a steady longer climb wouldn't it? I Just did one at 8.5 repeats to complete and the hardest thing was starting up again at the bottom. At least for me rhythm is key. Which also goes to steady gradient climbs or mixed gradient climbs. So many factors.

      Basically, choose the steepest manageable climb that is possible to do for a long duration if you want to complete it the fastest or with lowest fatigue. But too steep and you’ll need too much recovery and damage muscles and if your climb is less steep you will have to do too much work to overcome aerodynamic drag and rolling resistance. Aim for the steepest possible climb that’s manageable. And try to make it as constant a gradient as possible.
