GUCR Information

Held under UK:Athletics rules and with the kind permission of The Canal & River Trust, this non-stop 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 on race day, 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: 4687.

Race Introduction

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.
