What kind of engine do you have?

Type in your results from the four MaxCals engine tests. The chart plots your aerobic base against your top end, names your profile, and tells you what to train next to close the gap. Nothing you type leaves your device.

Not done the tests yet? Here is how to run and pace all four.

These are maximal efforts. If you have a health condition or any doubt about training this hard, check with a doctor first, and stop if you feel unwell.
