Get involved Events London to Cardiff 24 Hour Relay Challenge London Cardiff 24 is a team challenge like no other. As a team you will aim to run every step of the 160 miles from Twickenham in West London to the very centre of Cardiff. The route takes you along rivers and canals, through forests and towns, across fields, down public paths, and over bridges including the spectacular Severn Crossing. The terrain varies from tarmac to mud, gravel to long grass, and with the need to navigate your way along our route you will need your wits about you. When not running you are in your team minibus with your teammates, resting, eating, sleeping, talking and driving between checkpoints waiting for your runner to arrive. This is about the wits of the individual and the support and camaraderie of the team. It's a busy 33 hours, but worth it if you can make it all the way to Cardiff. Who can take part Teams can have between 8 and 12 runners, and up to 4 additional support staff (who are not permitted to run.) You must be 18 or older on, or before, Friday 9th June 2017 to enter. All pre-existing medical conditions must be declared to the organisers on booking. Costs and fundraising targets We are currently working with the event organisers to negotiate a charity rate for this event, but standard entry charges can be found here. How to book Until we have our charity booking rate confirmed we are unable to offer online booking. To register your interest in this event, please email Claire Rhodes in the first instance.
