Waypath: The run tracker that explains why you were faster

Hey Product Hunt! 👋 I'm Hugo. I built Waypath because every run tracker I used handed me a time and left me to guess what it meant. A 5:52 kilometre looks like a bad one — unless it was up a 5% grade, in which case it was a 4:30 effort and one of the best of your year. Waypath does that arithmetic. Grade-adjusted pace uses the published Minetti cost-of-running curve, so every split is graded flat-equivalent against the terrain you actually covered. Race predictions for 5K through marathon are built from the fastest efforts inside your real runs, not from an average pace that includes traffic lights — and each carries its own confidence, because a marathon extrapolated from a 5K is a claim about your speed, not your endurance. The rule I held myself to: where Waypath models a number instead of measuring it, it says so. Every estimated figure carries an "Estimated" badge and never mixes with sensor data. Where no honest model exists for a sport, it declines to invent one. Activities are private until you choose otherwise, per activity, and published routes are trimmed at both ends so a start point never becomes a home address. I'd love to hear from you: - Do you trust the numbers your current tracker gives you? - Which sport do you wish was treated properly instead of being logged as "running with different maths"? - What would make you switch trackers? Happy to go deep on the sports science or the privacy model. Thanks for taking a look! 🏃
