The Treble Challenge

Show dementia what you’re made of with the Treble Challenge.

Challenge yourself to swim, cycle AND run between 1 April and 31 December. Finish the events anywhere, in any order, and over any distance you like – and raise money to fund life-changing dementia research. It’s the triathlon with a real difference.
