The race starts and finishes in the same location at Stanborough Lakes in Welwyn Garden City. Youll need all your armour for the swim, which is two laps of the Stanborough Park amphitheatre for both events!
The swim is in Stanborough's southern lake, the bike course is undulating and the run features mixed terrain.
Helmets in place, Imperial and Metric combatants will follow the same bike course, but those tackling the longer distance will complete 4 rather than 2 laps. The Roman road-like Cole Green Way, linking Welwyn Garden City with Hertford, will feature on the run course, exploring the eastern boundaries of your empire.
