Leaving Team Sky behind to start Olympic training
Being a part of Bradley Wiggins's Paris-Nice win last week was amazing and as much a victory for me as for him.
Paris-Nice is a massive race and it has history. To go there as part of a British team, riding for Brad all week, and for him to finish it off in the time trial is a great feeling.

Hi, I'm Geraint Thomas and I cycle for a living. That's helped me win Olympic gold and travel the world. I've also suffered a few injuries, the worst being a ruptured spleen in Australia in 2004.

I'll be sharing my thoughts in the run-up to, and during, the Olympics, and answering a selection of your questions. Here are some tips on taking part and our
