A Duathlon is a multiple-stage competition involving the completion of three continuous and sequential endurance disciplines. While many variations of the sport exist, duathlon, in its most popular form, involves running, cycling, and running in immediate succession over various distances. Athletes compete for fastest overall course completion time, including timed “transitions” between the individual run, cycle, and run components.
To accommodate all diverse skill levels, there are a number of different distances for duathlon races. Sprint distances differ from race to race; nevertheless the other distances are consistent with the lengths shown below.
