Questions
What is a good 10K time for a 35-year-old man?#
Against the world best adjusted for age, a 35-year-old man scores 60% (local class) with 44:24, 70% (regional class) with 38:04, 80% (national class) with 33:18 and 90% (world class) with 29:36 over the 10K. Graded with AJ 2025.
What 10K time is 80% age-graded at 35 for men?#
33:18, which is 3:20 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 36?#
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 33 to 37 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.
