Duchenne UK is proud to be the title partner of the Duchenne UK Triathlon. Our aim is simple - to find treatments and a cure for children suffering with Duchenne Muscular Dystrophy, a muscle wasting disease. It’s the most common genetic killer of children, and most won’t live past their twenties. We believe that despite their weakening muscles these children are anything but weak - they are the World’s Strongest Boys. Join our team to use your muscles to help those whose muscles are weakening. 

We are looking for teams or individuals to take part in the World's Strongest Boys Triathlon next September. 

Use your strength and determination to save the World’s Strongest Boys.

Triathlon is one of the fastest growing sports in the UK. It offers variety, testing a combination of three different disciplines - swimming, cycling and running.

Event information

Our triathlon is held at Eton Dornay lake in Berkshire, an iconic venue from the 2012 Olympics, ideal for both first timers, and more experienced athletes. Start with a swim in the clear clean waters of the lake, before cycling the car free flat road circuit and then a final run along tarmac woodland paths.

You can choose to do a FULL triathlon, at Olympic or Sprint distance. Or you can form teams, and participate in one or more stage, in RELAY form.
