What about these 6 HR zones?
they do that for biking (for segments), so why not for running? just keep last 20 ? or 20 best ?
Still no map of starred segments in Strava?
how about adding this functionality to apps running on Garmin devices (or other supporting data from Strava)
privacy zone doesn't work, i set a new zone, my previous feeds were trimmed, but new tracks are visible in my privacy zone
