Superhero Tri powered by Marvel

16 August 2025 – Dorney Lake, Windsor

There are three super distances to choose from & many super ways to take part in these super-fun & flexible tri challenges. You can fly solo & take on all three stages (a swim, cycle & push/run for any tri newbies out there), share the fun in a team relay, or Superheroes can recruit Sidekick teammates to tow, push & pull them around the entire course! This summer we will be celebrating our super planet & all its natural wonders, so prepare yourself for a super-wild time!

A regular highlight of the day is our Celebrity Superhero Tri relay, where Superheroes can win the chance to unite with stars from sport & screen. More details coming soon!

Who can join the Superhero Tri missions: Everyone is welcome. All we ask is that all solo entrants, or at least one team member, considers themselves to have a disability of any kind.

When: 16 August 2025

Where: Dorney Lake, Eton College Rowing Centre, off Court Lane, Dorney, Windsor, Berkshire, SL4 6FJ

How: We want to make it possible for you to use anything you might need to complete your tri stage/s. For the swim, you can use flippers or floats or be towed in a vessel on the water (just remember to let us know about your vessel when you sign up). For the cycle, all types of adaptive bikes & wheelchairs are welcome. For the final run/push, everything from baby buggies to race runners & powerchairs are actively encouraged. For gadget inspiration, check out our Super Kit page.

Dress code: A Superhero outfit, of course! Check out some of these supersonic costumes to help you look & feel the part.

Super important: Please remember to register everyone taking part or assisting in transition as part of your super team when you book – Superheroes & Sidekick buddies – as only those signed up as an official team member will be allowed on the course &/or in transition on the event day. Each & every teammate, however big or small your role, will receive a T-shirt, medal & Super Kit Bag for your part in the super mission!

There are no cut-off times & all types of gadgets & gismos are welcome on the course. So grab those masks & capes, sign up & save the day!
