Welcome to the Centurion Triathlon the Vesuvius of multi-sport racing in south-east England. You have two races from which to choose: the 100-mile Imperial or the 100-km Metric.

Helmets in place, Imperial and Metric combatants will follow the same bike course but those tackling the longer distance will complete four rather than two laps. Trail footpaths and long, straight footpaths will feature on the run, which is either 2 laps for Metric combatants and 3 laps for Imperials.
