How can I change my vVO2max, especially if I start running again?

The vVO2max (the speed at VO2max) calculated by our algorithms is accurate in most cases, but it may vary depending on your performance profile.

For example, if a runner has a very strong 10K performance but a relatively weaker marathon performance, the model may identify a lower endurance level and therefore estimate a higher vVO2max. Similarly, if your current fitness level is significantly higher or lower than the performances entered in My Past Races (My Profile > My Running Experiences), the estimated vVO2max may not accurately reflect your current level.

To get a more accurate estimate of your vVO2max, you can perform a 6-minute test and enter the result in your Running Experiences (My Profile > My Running Experiences).

Simply run as far as possible for 6 minutes, then enter the distance covered.

For example, if you cover 1,500 metres in 6 minutes, this corresponds to a speed of 15 km/h. If you cover 1,200 metres, it corresponds to 12 km/h.

If you know your current fitness level well, you can also enter a fictitious 6-minute test result to set the value you want.

You can find more information about estimating your vVO2max with a 6-minute test here.

You can also change your vVO2max directly in My Profile > My Physiological Data > Change my vVO2max.
