Centurion Triathlon Herts

Welcome to the Centurion Triathlon – the Vesuvius of multi-sport racing in south-east England.

You have three races from which to choose: the 100-mile Imperial, the 100-km Metric and, for budding Centurions, the Legionnaire Sprint.

You’ll need all your armour for the Imperial and Metric swims, which are two laps of the Stanborough Park amphitheatre. Our Legionnaires have a more gentle 750m swim.

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. The Legionnaires will undertake a 20.3K Bike course with challenging hilly elements.

Trail footpaths and long, straight footpaths will feature on the run, which is either 2 laps for Metric combatants, 3 laps for Imperials and a 5K course for Legionnaires.

The innovative Centurion Triathlon will help you make the leap from sprint to standard, standard to middle distance or middle to long distance triathlon.

It will be one of the best race-preparation opportunities for longer distance events later in the season.
