Swim: Brooke Taylor, 15

Your story: “I was born with a tumour attached to my spine, which has left me with nerve damage to internal organs and down my legs. In 2015 I watched an event at Dorney Lake but was unable to take part as I was recovering from spinal fusion surgery. I was totally inspired, but found it tough watching as I desperately wanted to be one of the athletes. After two long years of being denied sport I was given the go ahead to get active again in July 2016. I've had to relearn to walk but this hasn't stopped me. Being part of a Celebrity Superhero team is the icing on the cake for me getting back into sport. To be able to go back and tell my surgeon how far I've come would be a really big thing for me. I like to defy the odds and I never give up. My motto is, 'If you have the ability to do it, then do it!’”
What it feels like to win a Celebrity Team place: “I’m over the moon and feel very privileged. August can't come quick enough.”
Most looking forward to: “Taking on my first ever open water swim!  I’m also looking forward to the atmosphere as I think it will be awesome.”
Your Kryptonite: “This also has to be taking on my first ever open water swim!”
Your Superpower: “The ability to achieve the impossible and to cancel the superpowers of others.”

Bike: Ben Warne (AKA Spud), 11

Your story: Ben attends Kingfisher School in Abingdon, Oxfordshire, a school for pupils with severe and complex physical and/or learning difficulties. Ben has a phenomenal passion for and knowledge of cars, especially Supercars, enjoys watching YouTube clips and loves riding his recumbent trike, particularly as he gets to race his brother Oscar. He has tried many sports, including badminton, tennis, football, swimming, basketball, golf and horse riding to name a few.
What it feels like to win a Celebrity Team place: Due to Ben’s global developmental delay and poor speech clarity he lacks confidence when meeting and working with new people. Competing in a team event will give him a sense of personal achievement.
Why Superhero Tri: It’s out of his comfort zone. Outside school, he's never competed in a sporting event.
Your gadget of choice: A recumbent trike.
Most looking forward to: Having people cheering him on in his first-ever public event.
Your Kryptonite: He's worried about underperforming and his legs becoming tired.
Your Superpower: His enormous kind heart. It fuels him with masses of energy and gives him the courage to step up and excel in his challenges.
