I'm not saying that I signed up for a running event in two months with almost no prior experience in running, but I'm also not _not_ saying it

Since I'm using OSMAnd (F-Droid) for bicycling navigation I can track the bike rides with it as well. I guess you could also use OSMAnd for running, I'm just not sure how detailed the tracked data is.
At the end of the year I'll take all the data and visualize it with Wanderer (https://github.com/open-wanderer/wanderer), I'm sure the OpenTracks data is also compatible with it!
