10 Mile Age-Graded Calculator
Ten miles is a classic distance in the UK and the US and a slightly odd one everywhere else. It has a dedicated factor table, so enter the time, your sex and your age on race day and grade it directly.

What is a good 10 mile time for my age?
The standards pages list the finish time that scores 50, 60, 70, 80 and 90% at every age from 18 to 99, straight from the same tables this calculator uses.
Questions
What is a good 10 mile time for my age?#
A 55-year-old man reaches 70% at 1:12:49 and 80% at 1:03:42. A 55-year-old woman needs 1:21:33 for 70% and 1:11:22 for 80%. The 10 mile standards page lists every age from 18 to 99.
Can I use this for a 10 mile split inside a longer race?#
You can, but the number will flatter you or punish you depending on how the rest of the race went. Age grading is built for a finish time over a measured course. A split is a training data point, not a record.
Which tables does this calculator use?#
Road results are graded with the Alan Jones 2025 tables, approved by the USATF Masters Long Distance Running Council in January 2025. Track uses WMA 2023. Both are single-year age tables, so the result reflects your exact age on race day rather than a five-year bracket.
What counts as a good age-graded percentage?#
The usual shorthand is 60% local class, 70% regional class, 80% national class and 90% world class. In a big-city marathon field roughly one finisher in eighty reaches 80%. Anything above 70% puts you in the sharp end of most races.
