Top comment
I built FormFactor because I was tired of switching between 6 different running calculators. Everything is in one place, runs in a single HTML file with no backend, and uses proper peer-reviewed correction models (Minetti, Ely, WMA 2015, WA 2022 scoring tables). Would love feedback — especially from runners who use Garmin or Strava daily. Drop a GPX file and see what it does 🏃
