A non-stop 145 mile journey from Little Venice in London to Bristol along the Kennet & Avon Canal towpaths and riverside trails. Runners must cover the whole distance within 45 hours, running, walking or mixing the two, and must meet checkpoint cut-offs along the way. It is a minimum-support event with long gaps between checkpoints, so entrants carry enough food, water and kit for each section.

Entries open at 10:00 on Saturday 31 October 2026 and close at 06:00 on Friday 18 June 2027. Entry is first come, first served through SiEntries with no ballot required.
No formal qualifying races are required. Preparation, training and respect for the challenge are essential, and previous long-distance experience will help you manage the distance and the 45 hour limit.
Canal Crew means the event volunteers are your crew, providing checkpoint food, refreshments and kit-bag support as detailed in the runner manual. Bring Your Own Crew means your own team supports you throughout, following the event crew and access guidance, bringing familiar faces and your preferred supplies.
Checkpoint gaps can be substantial. This is a minimum-support event, so you must carry enough food, water and essential kit for each section between checkpoints.
Retirement transport is available for Canal Crew entrants under the event arrangements. Check the 2027 runner information for the confirmed retirement procedures.
