PaceMaster - Master your pace. Shatter your Marathon PB.

Built by a runner, for runners chasing their next PB 🏃‍♂️ Hi everyone! I’m the developer of PaceMaster. As a marathon enthusiast, I often found myself juggling messy spreadsheets and complex math just to figure out my target splits or predict my finish time based on training weather. I wanted something cleaner, faster, and more scientific—so I built it. PaceMaster isn't just a calculator; it’s a strategy tool. Whether you are: 📊 Planning your training zones based on heart rate. 🔮 Predicting your 5K to Full Marathon potential. ⏱️ Calculating precise splits for race day. I've been thrilled to see that users who try PaceMaster really stick with it (we're seeing incredible long-term retention!), which tells me the "science-first" approach is working. I’d love to hear your thoughts! What’s the one feature you wish you had on your wrist or in your pocket during marathon prep? Happy running! 🚀
