Regarded by many as Britain’s premier Ultra, this is a145 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 eighteen 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.
