One of the toughest one day cycle events in the UK, the ULTRA challenges you to conquer an entire loop around London in one day.

Setting off early Saturday morning from Lee Valley, you will take in the famous London landmarks before leaving the urban cityscape behind you and venturing into the green fields and testing climbs of the North Wessex Downs. Once through Windsor, it is onto the Chilterns to conquer more incredible countryside before winding your way back through Epping forest to celebrate your momentous achievement in a blaze of glory back at Lee Valley!
