I just realized that although you can opt for “Trail Run” as an activity type before you record in Strava, there doesn’t seem to be any way to retroactively change a regular run to a trail run using the “Edit Activity” feature. All my activities are automatically created by my Garmin, which logs them as regular runs. Is there a workaround so that I can save them as trail runs (and, ideally, change some of the archived runs, when appropriate)?
