Show HN: I'm building a Strava alternative without all the social media crap
cubetrek.com
Some features include: a github-style calendar heatmap, 3D visualization of tracks (especially useful for hill climbs and mountaineous terrain in general), a world map displaying all your activities at once.
Excluded features: although you can share yoir tracks to the world, should you choose so, there are no friends, no likes, no comments, i.e. none of that social networking stuff. And no ads.
Any feedback is appreciated, let me know what you think, what to improve!
