The VO₂ Max Challenge

Fitness improves faster, and lasts longer, when you do it alongside other people. The challenge brings a group together to raise cardiovascular fitness over several months and follow progress on a shared dashboard.

How it works

  1. Estimate your starting VO₂ max with the Rockport walk test.
  2. Build more brisk walking and some harder effort into most weeks, at a pace you can sustain.
  3. Re-test at the check-in points and log your results on the challenge dashboard.

The dashboard opens on a separate site. Your results there are handled by that site, not stored on Tortoise Time.
