Radiohead bassist, Colin Greenwood joined 7000 other triathletes at the weekend to take on the 10th Blenheim Palace Triathlon.
The rock star was part of a team of athletes who took part in the Leukaemia & Lymphoma Research Blenheim Palace Triathlon to raise more than £90,000 to beat blood cancer.
Colin is pictured here with Dan Clarkson, father to 9 year old Scarlett who is being treated for leukaemia.
Scarlett was diagnosed in January 2011 at the age of 6. Her initial chemotherapy treatment was unsuccessful and she relapsed. She will continue to receive treatment for a further two years.
The musician and first-time triathlete posted his results form the race on his twitter page to thousands of followers.
The 10th edition of Blenheim Palace Triathlon welcomed 162 elite athletes including 63 senior, 61 junior and 38 youth triathletes.
