145 Mile Race

London - Bristol

KACR 2020 | Friday 24th July 2020 06:00 at London Paddington

KACR Information

Held under UK:Athletics rules and with the kind permission of The Canal & River Trust, this non-stop race is from Temple Meads Railway Station, Bristol, along the way-marked Kennet & Avon Canal towpath, Thames Path National Trail and Grand Union Canal towpath to Paddington Railway Station, 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: TBC

Race Introduction

Organised on the same lines as the GUCR, this 145 mile race follows canal, railway and river paths between Brunel’s Bristol Temple Meads and London Paddington stations.  Competitors receive comprehensive maps of the entire route which passes through the best of English countryside.  On the way runners “climb” the magnificent Caen Hill flight of 29 locks. For runners, it’s only a rise of 237 feet in 2 miles, but in canal terms it’s one of the “Seven Wonders of the Waterways” and well worth seeing.

KACR is the second 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.  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 – 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.
