I don’t know enough to know where the bug might be, but the interval data seems to offset on activities imported from Strava, compared to the original from my Suunto Spartan Ultra.
Normally I’ll record activities with the watch, which sends to Strava on my phone via the Suunto app. I’ll usually update the activity on Strava to fix the altitude data as my watch’s altimeter is a bit dodgy, and so I prefer to then delete the watch activity from intervals.icu and restore the automatically deleted matching Strava activity.
But I’ve realised today from an interval workout that the interval times in the Strava version on intervals.icu are offset or not matching the ones from the watch activity, so not lining up with the correct data. If I click View on Strava from the activities page everything seems ok on Strava itself though.
Here are a couple of screenshots from my little run today. I had a warmup for about 10:40 followed by 10 x 30s intervals and recoveries. On Strava itself this shows correctly:
The same workout imported from the Suunto all the interval splits look correct:
But the Strava workout looks like this after un-deleting, with the interval splits all offset by about -1.5 minutes:
I realise I may be doing something wrong or misunderstanding, but I thought I’d bring it up in case this is a bug.
Thanks so much for intervals.icu though. Just getting my feet wet still, but what a powerful tool!
