Included, Not Excluded – Every autistic learner. Every choice. Every future.

Superhero Tri powered by Marvel

Date: 15 August 2026
Location: Dorney Lake, Windsor
Registration fee: £55

Minimum fundraising: £100


Join the BeyondAutism team this August for the Superhero Tri Powered by Marvel.

The Superhero Tri is a  fully inclusive triathlon where you can fly solo or team up with Sidekicks to swim, cycle and push/run your way around the course.
With flexible ways to take part and no cut-off times, you can complete the course your way – supported, celebrated and powered by community (and plenty of capes).
We have just three charity places available, so if you’re ready to take on the challenge, don’t wait.

Choose your challenge

  • Sprint (150m swim, 3km bike, 1km push/run)
  • Half (400m swim, 10km bike, 2.5km push/run)
  • Full (750m swim, 20km bike, 5km push/run)

At BeyondAutism, we support autistic learners from 15 months to 25 years old through our specialist schools, services and outreach programmes.
