From: An empirical study of race times in recreational endurance runners
Race velocity in minutes per mile by age (a, adjusted for BMI and typical training mileage), BMI (b, adjusted for age and typical training mileage) and typical training mileage (c, adjusted for age and BMI). All models were also adjusted for sex and whether the runner trained with intervals or tempo runs. The tables underneath each figure represent the number of runners within the given age, BMI or mileage categories who ran a race of that distance. Yellow line: 5 km velocity; green line: 10 km velocity; red line: half-marathon velocity; blue line: marathon velocity
