Peaks

The Peaks tab shows the best (highest) power you produced in the session across common durations (e.g., 1s, 5s, 1min, 5min, 20min, 1h). It then compares those values to your historical bests.

Durability (learn more here) view compares your peak power not just when fresh, but after accumulating fatigue. In Peaks, you can display best values achieved after fatigue levels from 0 to 50 kJ/kg, in 10 kJ/kg steps.

Many athletes can hit strong peak numbers when fresh, but the real limiter in races and long training is what you can produce late, after repeated efforts.

This view helps you answer:

• “Can I still sprint after a hard hour?”

• “Does my 5-minute power drop sharply once fatigue builds?”

• “Am I improving my ability to produce power deeper into the session?”
