London Bikeathon

A charity bike ride in aid of Leukemia and Lymphoma Research which caters for cyclists of all ages and experience levels. Those whose weekends often involve lycra can take on a 100-mile route throught the Surrey Hills, or less ambitious bike users might prefer the 52-mile or 26-mile options, both of which fly past some of London's most impressive landmarks. Entry costs £25 (£50 for the 100-mile route) and includes fundraising packs, a training guide and a cycling t-shirt or jersey. Sign up in advance on the Leukemia and Lymphoma Research website.
