My cycling career started in 2005 when I purchased my first road bike and I was immediately hooked. Since then I have completed numerous cycling challenges including Ironman, Lands’ End to John O Groats, Mt Ventoux (all 3 ascents), London to Paris, the BBAR challenge which included a 12hour TimeTrial and more recently the Mallorca 312.
