Frequently Asked Questions
What is a good Half Marathon time for a 50-year-old woman?
The median is around 2:30:09. Faster than 2:07:37 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.
How can I compare my own time?
Use the age grading calculator to convert your result to an open-class equivalent.
How can I make this more accurate?
Submit your own result on the Endurometry submission page — it takes about 20 seconds and no sign-up.
