Age Grade Calculator
Compare your race time against the age-graded world standard for your age and gender.
How Age Grading Works
The calculator finds your age-and-gender world record standard for the chosen distance, divides by your time, and multiplies by 100. The result is your age grade — a percentage that lets you compare performance across ages, genders, and distances on a level scale.
Performance Tiers
World class: 90%+. National class: 80-89%. Regional class: 70-79%. Local class: 60-69%. Recreational: under 60%. These tiers are widely used in masters running communities to set goals and compare athletes.
