Everyone knows that the best way to improve as a cyclist is to do power based interval training. However its not always easy to motivate yourself to ride halfway up and down the same hill 8 times in a row. Intervals.icu automatically detects intervals so you can ride your favourite route, punish the rollers and still get good stats to track your progress. Forgot to hit the lap button? No problem!
Heartrate based interval detection is under development.
