What is it?

Its London’s original and best Urbosportive!  Or in plainer terms, its a bike ride around a route marked out for you around some challenging terrain, right here in the capital.

The format is simple: we meet at the Gipsy Hill Tavern, depart for cobbles and climbs aplenty before returning to SE19 for food, drinks and BIG SCREEN PARIS-ROUBAIX and a raffle with BIG PRIZES.

Hope to see you all again on Sunday the 9th of April 2017 at The Gipsy Hill Tavern, London SE19.

Registration opens at 08:00am.

Our guideline donation is £15 and this has remained the same since our first event in 2009. The generosity of our punters has meant over £30,000 has been raised for the Evelina Children’s Hospital.

Entry in previous years has filled up quickly and due to the capacity of our HQ venue is limited to 400 riders.


As ever our target charity is Evelina London Children’s Hospital and all profits from the event go their way.

You can donate ahead of the ride by visiting our donation page.
