Frequently Asked Questions

What is a good Half Marathon time for a 45-year-old woman?

The median is around 2:26:29. Faster than 2:04:31 puts you in roughly the top 20% of your age group.

Where does this data come from?

Baseline estimate — not enough verified submissions for this age group yet. Each figure blends a published baseline model with real anonymous submissions using a shrinkage estimator: with few samples the value stays close to the baseline, and as submissions accumulate the real data takes over. Groups with fewer than 8 submissions show the baseline only.
