THE COURSE

The Venue – Kimbolton School

Kimbolton School provides a fantastic setting for our triathlon, with its beautiful grounds and sporting facilities making it an ideal base for a day of swim, bike and run. The school setting also provides a welcoming, supporter-friendly environment, with plenty of opportunity for family and friends to come along and enjoy the action.

Transition

Our transition area is located on a grass playing field, providing plenty of space to rack your bike and organise your kit before setting off on the next stage of your challenge.

The Bike

Enjoy the beautiful surrounding Cambridgeshire countryside as you tackle the bike course. You'll head out onto quiet country roads, offering a great opportunity to find your rhythm and enjoy the ride.
Remember, this is a non-drafting event, so make sure you're familiar with the British Triathlon drafting and overtaking rules.

The Run

The final discipline takes you around the beautiful playing fields and farm tracks. With a friendly atmosphere, well-marked routes and supportive marshals, you'll have plenty of encouragement to keep you going all the way to the finish line!
