Celebs tackle London Triathlon
Spice Girl Melanie Chisholm was joined by British Olympic champions and a host of television presenters in tackling the Virgin Active London Triathlon.
Mel C completed the VIP Sprint event - a 750 metre swim, 20 kilometre bike ride and five kilometre run - in one hour, 31 minutes and 20 seconds and then hinted she might tackle the full Olympic distance next year.
"Once again the Virgin Active London Triathlon has been an incredible day," said the pop star.
"This is my second year competing and will definitely not be my last. Roll on next year... Olympic distance?"
Olympic boxing champion Nicola Adams and Jade Jones, who won taekwondo gold at London 2012, both enjoyed expanding their sporting horizons.
Adams, the first woman to win an Olympic boxing gold, said: "I feel really good after doing my first triathlon and would definitely love to do it again next year."
Jones said: "I really enjoyed taking part in the Virgin Active London Triathlon. Hopefully it will inspire more people to take part in something which they wouldn't normally do."
Former Wales rugby captain Gareth Thomas completed the cycling leg in the team event to help raise money for former teammate Matthew Watkins, who was recently diagnosed with cancer.
Stavros Flatley, who rose to fame through Britain's Got Talent, Cathryn Dresser from the Great British Bake Off and television presenter Zoe Hardman all took part.
