Challenge Run - One score. One leaderboard. Real accountability.

I built Challenge Run because I wanted to share a great run — not a spreadsheet of pace and distance data, just the moment. So I built one number: a score that captures how hard the effort was, regardless of distance or pace. Your friends look at it and they know. We're in early access and actively looking for early adopters who like the idea and want to help build it. If you've ever wished your running app made the effort feel more social — more worth showing up for — this is for you. We'd love to have people in who care about where this goes.
