FTP is the highest power you can sustain for ~1 hour — the anchor of all power-based training. The 20-min test (all-out × 0.95) is the most practical. Test on the same bike/power meter, fresh, every 4-8 weeks. 80% of weekly volume should be Z2 (polarized/pyramidal training).

Calculation steps

  1. 1FTP = test power × 0.95 = 250 × 0.95 = 238 W
  2. 2W/kg = FTP ÷ weight = 238 ÷ 70 = 3.39
