PIPPA Middleton was one of the head-turning stars to compete in this year’s Blenheim Triathlon.

She was one of 5,5000 competitors and ran the 5k distance as part of a team relay.

Formula 1 driver Jenson Button, also took part in the GE Blenheim Triathlon, along with his girlfriend Jessica Michibata.

Former Olympic, European and Commonwealth 400m champion Iwan Thomas added some more star quality to the start line, along with 55 Degrees North actor Mark Lewis-Jones.

Mr Button said: “It was fantastic, and a tough challenge. It’s amazing to be able to race at a beautiful venue in such a well organised event.

“It was wonderful for Jess to race in front of her mum and our friends with the support of so many spectators.

“We have been to races in Kona, Honolulu and all over the world, but to me, as this is my home country, it is the most beautiful.”
