A MAF test is roughly a 35-minute run at your ceiling heart rate, on the same course every time — the cleanest signal of real aerobic progress, since distance, terrain, and effort stay constant.

This is a MAF test (same course)

If you enter a heart rate, MAF vs Other is set automatically from your ceiling and duration — Tempo/Interval/Race need to be picked manually, since HR alone can't tell them apart. Retag anytime by tapping the category on the run in History.
