Power zones for a 310W FTP
The seven Coggan power zones — the canonical zone model every power-meter-based training system uses — calculated for an FTP of 310 watts. Plus common workout targets (sweet spot, threshold, VO2max, over-unders) in watts so you don’t have to do arithmetic on the bike.
Coggan zones at 310W FTP
| Zone | Name | % FTP | Watts | Purpose |
|---|---|---|---|---|
| z1 | Active Recovery | 0–55% of FTP | 0–171 W | Promote recovery; shake out fatigue without adding load. |
| z2 | Endurance | 56–75% of FTP | 174–233 W | Build aerobic base — mitochondrial density, fat oxidation, capillary growth. |
| z3 | Tempo | 76–90% of FTP | 236–279 W | Extend endurance with a harder stimulus; race-pace for long events. |
| z4 | Lactate Threshold | 91–105% of FTP | 282–326 W | Raise FTP; improve lactate shuttling and sustainable power. |
| z5 | VO2max | 106–120% of FTP | 329–372 W | Increase maximal aerobic power; push VO2 ceiling. |
| z6 | Anaerobic Capacity | 121–150% of FTP | 375–465 W | Develop anaerobic system; critical for surges and attacks. |
| z7 | Neuromuscular Power | 151%+ of FTP | 468+ W | Train short-duration maximal efforts — sprints, jumps. |
