Running Pace API
A running-pace calculator as an API. Work out pace and speed from a distance and a time (pace per kilometre and per mile, plus km/h, mph and m/s); compute the finish time from a distance and a target pace; predict your time at another distance using Peter Riegel's formula (T2 = T1 × (D2/D1)^1.06) — e.g. estimate a half-marathon from a 10K; and generate a split-time table for even pacing. Times accept seconds, M:SS or H:MM:SS. Perfect for running and fitness apps, race planning, training logs and pace bands. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 5 endpoints. Distinct from general unit conversion and from body-metric (BMI/BMR) health calculators.
