Don't get me wrong. I love a good family-friendly hike as much as anyone else. But sometimes you want to be grimacing, not smiling, on the trail.
SufferTrails is that, and not much else. All trails not allowed.

This is cool. I built windygap.app which generates trails based on what you're after. Would be interesting to use that engine to generate more SufferTrails across the world.
