Great Yarmouth

Pack up your sword and shield as well as your swim, bike and run gear for the inaugural running of this latest Centurion distance event that is destined to become one of the most popular triathlons on the East coast of Britain.

The Centurion Triathlon is based on the seafront at Great Yarmouth, and has the options of a 100km Centurion triathlon, or an Aquabikus for those wishing to complete only the swim and bike legs.


From a beach start the swim is a 1.5km point to point 1.5km tidal swim along the beach.

Please note that the swim is in the sea and will be more challenging than a typical open water or pool swim. Wetsuits are not compulsory but are recommended subject to British Triathlon temperature restrictions, though the sea at Great Yarmouth is unlikely to exceed the maximum temperature allowed for wetsuits.


The cycle course takes athletes North along the seafront before heading inland onto the scenic roads of the surrounding countryside. The Centurion course completes 3 laps of this spectacularly fast course before heading back to the seafront to complete the 84km course.

Although we aren’t putting a time limit on the course, this bike course will include a managed junction as the route leaves town. This junction will allow athletes an unobstructed ride through for up to 45 minutes after the leader has passed. Any athletes more than 45 minutes behind the leader at this point will be allowed to continue, but have to obey the traffic lights at this junction. On the way back in to town this junction does not affect the route.

Run Course

After racking your bike it will be time to run!

Athletes will run out of Transition and complete 3 x 5km laps of the seafront promenade, providing great opportunities to be cheered on by spectators and supporters to complete the 15km run and hailed a hero as you charge through the finish line.
