Swim: Sally Valentine, 39

Your story: “I’ve done marathons and half marathons and used to run 5ks, 10ks and 10 milers in local events most weekends. I loved just getting up in the morning and being able to go for stress-free runs come sun, rain, wind, snow, the lot. But after four or five years of struggling and knowing somethings was wrong, I was diagnosed with MS. I still have the urge to do something so it's the gym & the pool, but to have that feeling of taking part in an actual event again is fantastic.”
What it feels like to win a Celebrity Team place: “Really, really lucky and grateful.  I haven't been able to take part in an event for the past four years, which was one of the reason I entered Superhero Tri. To win a place with a Celebrity Team Captain has made it so much more exciting.”
Most looking forward to: “Everything! It’s not every day I get the chance to be a Superhero and have my own avatar!”
Your Kryptonite: “The heat (that's if we get any sun in August) but I'm sure the water will cool me down!”
Your Superpower: “My enthusiasm! I literally cannot wait!”
