The 12 Minute Run test
If you have 12 minutes spare, plus warm up and cool down time, you can find out: how aerobically fit you are, a theoretical VO2 Max figure and how well you do for your age. Run, walk, crawl as far as you can in 12 mins. Then compare here.
If you want a VO2 Max “figure” try this (very crude) calculation:
VO2max = (22.351 x kilometers) – 11.288 = mL/kg/min
Then look yourself up here:
Try not to kill yourself. You may need to build up running times, and possibly get medical clearance. Some need to walk. It doesn’t matter if your first go is a poor result. Use it to motivate you to get better.
