Hey Product Hunt 👋 I built **RunnersLab** because I kept needing simple running calculations without digging through cluttered websites, spreadsheets, or apps. It started as a small pace calculator and slowly turned into a collection of **100+ free tools for runners** — pace calculators, race predictors, training pace tools, heart-rate calculators, pace charts, treadmill conversions, and even a few deliberately ridiculous ones like *Could you outrun a zombie?* 🧟 The idea is simple: **useful running tools, fast, free, and without creating an account.** I’m still actively improving it, so I’d genuinely love to hear what you think — especially which tools you find useful, what feels confusing, or what you think RunnersLab is still missing. Thanks for checking it out! 🏃
