Notes
- FTP is the highest power you can hold for roughly an hour; a 20-minute test times 0.95 is the common field estimate.
- Level bands are rough guides for flat-terrain racing fitness, not selection criteria.
- Educational estimate for sport and training purposes, not professional coaching or medical advice.
