Your 7 Coggan training zones with watt targets
Based on FTP of 335W
| Zone | % of FTP | Watts | Purpose |
|---|---|---|---|
| Z1 Active Recovery | < 55% | < 184W | Very easy spinning for recovery between hard days |
| Z2 Endurance | 56–75% | 188–251W | Conversational pace — builds aerobic base |
| Z3 Tempo | 76–90% | 255–302W | Comfortably hard — improves lactate clearance |
| Z4 Threshold | 91–105% | 305–352W | Race pace for ~1 hour — the key training zone |
| Z5 VO2max | 106–120% | 355–402W | 3-8 minute intervals — boosts oxygen uptake |
| Z6 Anaerobic | 121–150% | 405–503W | 30s-2min bursts — develops high-end power |
| Z7 Neuromuscular | > 150% | > 503W | Max sprints <15s — pure neuromuscular power |

Marginal gains matter now. Dial in nutrition timing, sleep quality, and heat/altitude adaptation. VO2max and anaerobic work yield the biggest returns at this level.
Your sweet spot range is 295–315W — the most productive training intensity for time-crunched athletes. Two 20-minute sweet spot intervals per week will steadily raise your FTP.
Keep endurance rides below 251W (Z2 ceiling). Going harder on easy days is the most common training mistake — it adds fatigue without the adaptation stimulus of true interval work.
