To avoid disappointment at the end of your race (as well as during), set your expectation to low, and then halve it!


Canal & River Trust

Race Introduction

Organised on the same lines as the GUCR, this 145 mile race follows easy to navigate canal, river and railway paths. Competitors receive comprehensive maps of the entire route which passes through some of the best of English countryside. On the way runners “descend” the magnificent Caen Hill flight of 29 locks, a drop of 237 feet in 2 miles, one of the “Seven Wonders of the Waterways” and well worth seeing.

KACR is the second of the three race 2025 Canalslam series totalling over 400 miles.  Each race can be entered as a one-off, but competitors completing all three receive a special award. Entrants should note that checkpoint/feed-stations are further apart than in these other races.  Again there are no entry qualifications, but a schedule to fit the 45 hour overall time limit is required.

  • Easy route navigation – detailed maps and a canal to follow.
  • Plenty of support – feed stations approximately every 25 miles, and buddies allowed from the 77.5 mile point.
  • 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.
