Canalrace Ultra Events are here for all abilities. Whether a first time novice or world class star, you are welcomed to these challenges by some of the friendliest volunteers you’re ever likely to meet.

If you’re thinking, “It’s a long way, I’ve never run that far before.” Well, no-one has until they give it a go! Maybe it’s just because you haven’t tried. What’s the worst than can happen? Should you have a bad day and have to retire, we’ll give you a lift to set you on your journey home – a ride in our sweeper’s bus really isn’t so bad.

If navigation is an issue and you find it hard to follow a route, we’ve put a canal or river next to almost all of it for you to follow. Just to be doubly sure, you’ll get detailed, waterproof maps of the whole route along with your other race information.

If carrying your kit all that way is daunting, fear not! We have experienced handlers who take pride in making your bag available at each of the checkpoints along the way. Whilst there you’ll have time for food, drink, a rest, and even a change of kit, and still be inside our generous cut-offs.

Before you enter, please ensure you have:-

• Considered carefully whether you wish to enter as Supported (with your own crew) or Unsupported (tended by our checkpoint crews).
• Read the Race Information
• Read the Pre-Entry Notes
• Read the Terms & Conditions
• Read the FAQs

The 2025 race calendar including GUCR 2025 race and entry opening dates is available here. Keep an eye on the News section for updates and announcements, in particular the 2025 Canalrace Season Entry Notes.

N.B. deadline for pre-registration via SiEntries is end of 31st October 2024. Places will be allocated by names being drawn from a “hat” early in November. All applicants will be notified of the result soon afterwards.

The option to enter more than one race, or all three for the Canalslam will be shown. There are additional questions to be answered for the GUCR so we can record those intending to complete the Canalslam and also to identify those persons that were unsuccessful in last year’s draw – who will receive an extra ticket in the hat.

To significantly improve chances of success at the draw, we encourage choosing the Supported (with own crew) category. Due to the high demand for an Unsupported (tended by organisers) place, versus the very limited places available.
