Built a fitness app that turns every run into competition — launching on PH today

Hey PH,

I'm the founder of Challenge Run. I built it because I finished a great run pushing my son in a stroller and wanted to share it — not send everyone a spreadsheet of pace data they didn't ask for. Just the moment. And there was no good way to do that.

So I built one number. A score that captures how hard you worked — distance and pace are how you earn it. Your friends look at it and they know.

What it does:

- Single score per run — legible to anyone at a glance

- Social feed showing friends' and family's activity

- Weekly state leaderboards

- Daily structured challenges

- Buddy system for accountability

We're in early access and looking for runners who want to help shape where this goes. No VC money, no stakeholders — just a solo founder who runs.

Launching today: https://www.producthunt.com/post...

Happy to answer questions about the product, the stack, or building solo as a new parent.
