Questions
What is a good 10 mile time for a 25-year-old woman?#
Against the world best adjusted for age, a 25-year-old woman scores 60% (local class) with 1:18:40, 70% (regional class) with 1:07:26, 80% (national class) with 59:00 and 90% (world class) with 52:27 over the 10 mile. Graded with AJ 2025.
What 10 mile time is 80% age-graded at 25 for women?#
59:00, which is 3:40 min/km. 80% is the usual shorthand for national class. In a big-city marathon field roughly one finisher in eighty reaches it.
Does the target change at 26?#
Yes, a little. The tables are single-year, so every birthday moves the target a few seconds over a 5K and a minute or two over a marathon. The rows for 23 to 27 on this page show the slope.
Where the numbers come from
Age grading divides the world best for the distance, adjusted for age and sex, by your time. 100% is that world best. The road factors are the AJ 2025tables, approved by USATF’s Masters Long Distance Running Council. The methodology page has the formula, and this post shows what 80% looks like across every distance.
