Castles Challenge Triathlon 2018 Participant Information


1900 metres. The swim course commences with a beach start before entering the water for 1 lap.

There will be a water safety team consisting of kayaks and rescue boats and we are fortunate enough to also have an RNLI inshore lifeboat attend.

The run up the beach to Transition will be approximately 300 metres based on the tide on the day of the event.



90km. The bike course is 2 laps of a 45km circuit and there’s no big hills! You’ll pass Race HQ after completing the first lap, so you’ll be guaranteed plenty of support. There’ll be a feed station located at Race HQ as you complete your first lap.

The course runs in a clockwise direction.



21km. The run course consists of 3 laps of a stunning coastal route that heads along the cliffs to Budle Bay overlooking the beautiful sandy beaches before returning to Bamburgh Castle.

Upon commencing the run section, competitors will head out to start the first of 3 laps with each lap completed once they have reached the turnaround point at the cricket pavilion. The total run distance is 21km (13.1 miles).

On each lap you’ll twice pass the Race HQ, so there’ll be plenty of support to help cheer you along!
