My fitness training load is buggy

Hi, my fitness training load is buggy. It suddenly stopped measuring about a month ago and says, "Needs more data." I usually ride my bike once or twice a week. What can I do?

iPhone 15 Pro Max, iOS 26

To rule out a software issue inside your backup data, the next step would be, erasing the watch and pairing it again, setting it up as a new device. You will only lose your created Watch faces and may have to activate the cards in your Wallet app again.

Then test the Outdoor Cycle workout again.

Thanks for the advice, I tried but no results. The other workouts (walking or running) work regularly (both with the native Apple app and with other apps:) only the bike doesn't work.

Did you already try to force restart your iPhone and Apple Watch, to make them sync again?

Can you see more recent workouts in the Health App on your iPhone?

To force restart your watch, press and hold the Digital Crown and the Side button together for about 10sec, until the Apple logo comes back again.
