Hi Product Hunt 👋 I'm a runner and a solo developer. Every time I signed up for a race I ended up in the same spreadsheet: take my last 10K, guess a marathon time, work out splits, look up training paces, convert treadmill speed… and do it all again a month later. PaceForge is that spreadsheet turned into an app I actually want to open: • Race Predictor — enter one recent result, get predicted times for 5K to marathon (Daniels & Gilbert / Riegel) • Training Paces — easy, marathon, threshold, interval and repetition paces from your VDOT • Race Plans — even or negative splits, per-mile or per-km, saved so you can tweak them on race week • Heart-rate zones — Tanaka / Karvonen, with the actual citations on the screen • Treadmill converter, track splits, PR log Things I cared about that most pace apps don't do: – Fully offline. Nothing leaves your phone. No account, no login. – 7 languages (EN, ES, FR, DE, IT, PT, JA). – Free. It shows a few ads to stay that way; that's the whole business model. It's iPhone-only for now. I'd love to hear what you'd want next — more distances, Apple Watch, a web version? Brutal feedback welcome. Thanks for looking!
