Hey Product Hunt! I'm Gareth, the maker of Gauntlet. The idea came from a simple frustration: fitness accountability is broken. I've made verbal bets with friends a dozen times — "loser buys dinner if I don't hit 50km this week" — and they never actually happen. Nobody tracks it, nobody pays up. Gauntlet makes those bets real. Connect Strava, pick a challenge (run/cycle/swim), set the distance, stake some USDC, and your friend accepts. Strava data auto-verifies the result. Winner gets paid on-chain. No manual settlement, no "I forgot", no awkward chasing. The tech: on-chain USDC on Base, Strava webhooks for automated verification, non-custodial so we never hold your money. The whole payout flow runs on-chain — we just trigger it. I've been running it for a few months. The behavioral effect is real — even a $10 stake changes how seriously you take a run. Loss aversion is a more powerful motivator than any fitness app streak. It's free to join. You only put money in when you enter a challenge. Happy to answer any questions — ask me anything about the tech, the design decisions, or what's coming next. And if you try it, I'd love feedback. gauntlet.bet

using Strava as the oracle for fitness bets is actually smart, no disputes no trust needed. and yeah even a $10 stake changes behavior, loss aversion just works. what stops someone running a Strava bot to fake the data?
