Estimated VO2 Max



Could TrainerRoad provide an Estimated Vo2 Max using the ramp test and some other formulas?

Asking for a friend… :smile:


How to Calculate Your Own VO2Max via Hunter Allen

Relative VO2Max = [(10.8 x W)/M] + 7


W = watts
M = cyclist weight in kg
VO2Max = mL/(kg x min)


Cool. And to simplify more, you can use the watts per kg on your TR profile screen:

= 10.8 x WpKg + 7

(assumes your weight and ftp are correct in TR)


As noted in the comments to the article linked above, this formula will most probably underestimate the V02max for trained ppl.

As an anecdote, this formula estimates my V02max to be 52, but when I measured my V02max in a lab it was 67…


It was 12 higher in the lab for me


Any idea how Garmin estimates VO2 max?


@AndyGajda Garmin uses FirstBeat technology to estimate VO2max:


Which is also very inaccurate, at least for me. Although YMMV :slight_smile:


I’m using Edge 520 and Stages single-sided PM, and the Garmin/Firstbeat VO2max estimate seems reasonable but I’m not planning to have it lab tested to verify.

After reading Joe Friel blog posts and books on the topic, here’s one:

All I’ve been able to gather from my VO2max estimate is that I didn’t win the genetic lottery for aerobic capacity. But thats something I’ve known for almost 40 years, since running cross country in high school.


First off, are you trying to estimate it for specific VO2 Max based workouts or just out of curiosity? The actual VO2 Max figure is widely useless in training and racing. While watts generated at VO2 Max capacity can be highly useful for targeted workout planning purposes and some racing applications such as a pursuit on the track or a short 5 min finishing climb. As to being useless in racing as a figure, the reason is that everyone is able to tolerate different amounts of pain and process biological waste products more or less efficiently. For example the Tour de France winner or even world champion pursuit winner on the track is not just the person with the highest tested VO2 Max. For example the highest tested VO2 Max athletes have been cross country skiers, while they could be good racers, due to specificity the high vo2 Max does not directly apply to cycling. Essentially your body can process high amounts of oxygen per minute, that is a metabolic measurement. However, a racer that can tolerate insane amounts of lactate, or really the hydrogen ions that build up in your muscles which causes the associated pain, can potentially produce far greater watts even at a lower tested vo2 Max. On one of the podcasts they alluded to this, I believe it was Jonathan, that mentioned in a lab he tested at 17 mmol at Lactate Threshold, now I’m that case the metabolic rate being tested is different but the same premise applies. Some athletes would not even be able to turn the pedals at blood lactate numbers that high, while some can endure crazy high numbers. However, in both cases regardless of the test, the ability to put watts into the pedals which actually powers the bike forward is a better measure of performance.

In this case, an all out 5 min effort is the best proxy for determining ability at VO2 Max. It will very closely approximate your maximum power sustainable at your VO2 Max level. Precise training plans and the performance enhancements that can result from following such plan can lead to very useful and applicable improvements on the bike. Both in training, but also more importantly in the movement of truth, either in getting into a break, or a late race attack with 2 laps to go, or a leg breaking climb at the end of a race.


TrainerRoad @Nate should be able to give us the Vo2 Max from our Ramp Test’s!

Using the math from the video…

For my age, I’m rated as Good!
