Running by the Numbers
Average times, real benchmarks, and the pace math — so you know where you actually stand.
Start here
OpenCrunch turns running into numbers you can compare. Pick your distance:
- Average marathon time & what counts as good — by sex, with percentile benchmarks.
- Average half marathon time & what counts as good — by sex, with benchmarks.
- Pace calculator — turn a goal time into the exact pace and splits, and see your equivalent times at every distance.
More — 5K and 10K standards, age-grading, and a VDOT calculator — are on the way.
A note on the data
Figures are approximate and drawn from large public race-result analyses (notably RunRepeat's study of millions of finishes). Averages vary by dataset, race and region — treat them as benchmarks, not absolutes.
