The Long Run - Uphill


The 2024 GUC race will once again be “Uphill” from London to Birmingham.

Held under UK:Athletics rules and with the kind permission of The Canal & River Trust, this non-stop 145 mile race is from Gas Street Basin, Birmingham, along the way-marked Grand Union Canal Towpath to Little Venice, London. Competitors who must be 20 or over, are recommended to have their own support crews, but up to 50 Unsupported runners can be catered for by the Organisers, Canalrace C.I.C.. Trail Running Association Permit Number: TBC

Regarded by many as Britain’s premier Ultra, this is a 145 mile continuous race from Gas Street Basin in the Centre of Birmingham, to Little Venice in the heart of London. Run entirely on the waymarked Grand Union Canal Towpath, the easy to navigate, and relatively flat route, takes runners through a variety of urban and rural scenery – there should be something for everyone.

This is a race organised by enthusiasts, for enthusiasts. It is definitely “old school”; definitely low key, and definitely a long way. There are no entry qualifications (other than that you must be over twenty and willing to give it a good try) so runners of all abilities are welcomed. Entrants should, though, be aware that they must be able to maintain a rate of progress in line with an overall time limit of 45 hours.

GUCR is the first of a three race series “The Canalslam” totalling over 400 miles. Each race can be entered as a one-off, but competitors completing all three receive a special award.

  • Easy route navigation – detailed maps and a canal to follow.
  • Plenty of support – snacks and drinks every 10 –15 miles.
  • Transport for retirees – a lift to the nearest station for anyone having a bad day.
  • Easy to meet cut-off times – simply in line with the generous overall time limits.
  • No qualification – previous experience of just a marathon has proven enough.

Thank you for your interest to compete in the 2024 GUCR. Below is a guide to the two-step entry process.

Please visit the GUCR 2024 How to Enter page on the website for full and up to date race information. Pre-Entry NotesTerms & Conditions and Rules should be read and fully understood before entering.

STEP 1: PRE-REGISTER on SiEntries by the end of 31st October. No payment is taken. An automatic email will be sent to confirm race pre-registration. Make sure to enter the correct email address belonging to the runner being pre-registered.

The lottery Draw will be conducted at a pub in early November, full details of the time and location will be provided to entrants closer to the time. Runners are welcome to attend, witness and participate. Those successful in the Draw will be 'Invited' back to SiEntries by email within a few days after the Draw in order to make payment and confirm their place. Unsuccessful entrants will also be notified.

Note: 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.
