I am an eilte professional triathlete and British duathlon champion 2011 and 2012. I'm a member of the British triathlon team and the Trigold squad, and I'm very proud to be British Duathlete of the Year 2012.
I started as a runner, then turned cyclist, and finally added swimming to the mix to become a triathlete.
Last year I competed in UK, Peru, Brasil, Ecuador, Africa, France, Spain and Canada.
I'm also proud to be an ambassador for the Wells Sports Foundation.
I've started using booost to help combat the feeling of light headedness as I come out of the water between hard 100 sets.
Mark will give us more feedback as he uses booost in various situations.
