Tools made for runners
Finish Line Labs offers free calculators for runners who want quick, practical answers about race times, training paces, splits and treadmill speeds.
Our conversion tools use standard distance/time arithmetic; race-time estimates rely on published formulas and may not reflect individual training adaptations or race conditions. Double-check important calculations before relying on them for a race plan.
We aim to keep calculators free and easy to use. Future advertising or affiliate relationships will be disclosed clearly and kept separate from calculator results.
