Thousands of lycra clad cyclists will be taking part in the London Bikeathon 2014 today. All the money raised from the event will be going to Leukaemia and Lymphoma Research.
Riders can choose to do the 26, 52 or 100 mile routes. Though online registration for this event has closed, cyclists can still sign up in person on the day.
