I have vivoactive HR and one of my routines is doing a number of 400m sprints with a rest of 1:20 in between. I want an activity where I can set up to record my 400m sprints however I cannot find one, I can find only find some that can set up intervals of distance or time only but not in combination together. I created my own workout in the garmin connect app for this but unfortunately it says my device is not compatiable. So would anybody know of a downloadable app or solution for my scenario?
