Best efforts are found automatically — you don't mark them. For running, walking and similar sports we look for your fastest time at standard distances such as 400 m, 1 km, the mile, 5 km, 10 km, the half marathon and the marathon. For cycling we look for your best power over set durations instead.
You don't need a race or a lap button. We slide a window of the target distance along the activity and keep the fastest stretch, so a fast 5 km inside a long run counts.
The list shows your fastest time across your recent activities, not only this session. A trophy means it is also your all-time best at that distance. A badge next to a time means it was not a clean result — for example a gap in heart-rate data, a downhill assist or a distance jump in the GPS. Tap the badge to see why.
The power curve shows the most power you held for each duration, from a few seconds up to hours, taken from one ride. Short spikes sit on the left and sustained output on the right. It describes the shape of your effort; it is not a target and not a comparison with other riders.
Treat one result as a measurement, not a verdict. A time that is missing means that distance was not found in the activity, not that you didn't run it well. Compare efforts over weeks and in similar conditions.
