Power zone duration calculations

Hi, one day’s worth of rides are rolling up to 13hrs of z1+2. It should be nor more than 1.5hrs. Any idea why / how to correct? Thanks

Something went wrong with this ride: Intervals.icu

You need to crop it on Strava and then do Actions → Sync on the ride timeline chart to reprocess it.

David! again you’re prompt and accurate. thanks, i’ll keep an eye out for that in the future
