James Allen started mountain biking as a teenager, but turned to road cycling as an adult to strengthen the leg muscles following a cruciate knee injury. Since then he has taken part in a range of road cycling events including sportives, time trials and road races. He has a particular liking for hill climb events due to their purity, but also their severity. He now rides around 10,000 miles a year.
