Rundida Mcp

xweaponx7/rundida-mcp

Connects Claude to RunDida's 92 running calculators and 46 training guides through their free JSON API. You get ten tools: browse calculators and guides, fetch marathon event details with weather forecasts, and run local computations for pace/time/distance math, race predictions using the Riegel formula, and heart rate zones via the Karvonen method. The compute tools run instantly without API calls. Data tools hit rundida.com with 30 minute caching. Useful when you need running math in conversation, whether that's splitting a 3:30 marathon into per-mile paces or estimating a marathon finish from a 10K time.
