It's not what you think.

The Times: Strava, the online fitness tracking platform that has become a favourite of cyclists and runners, has acquired Fatmap, an outdoor navigation tool for sports.

Just had a quick look and appears to be an app giving 3D views of local areas.
Mountain biking listed as one of the activities.
Is anyone using this?
Is it any use?

Just had an email in saying Fatmap is now part of Strava.

Gave up Strava years ago, so won't be checking it out now I doubt

I used the free version of Fatmap when I walked the Camino Primitivo last year and found it very useful. If I was going to be walking or cycling a lot abroad, especially away from marked trails, I'd happily pay for it.
