River Ayr Way Challenge

The River Ayr Way Challenge is a long-distance running event held in Ayrshire, Scotland. Participants follow a route that begins at Glenbuck Loch and concludes at the Riverside Stadium in Ayr. The course spans a total distance of 40 miles and takes runners through various rural landscapes and scenery along the River Ayr.

Participants can choose from the following categories:

  • 40 mile individual ultra marathon
  • 40 mile relay for teams of two or three people

The course is divided into three primary sections. The first section from Glenbuck to Sorn covers 17 miles on rural, mainly off-road paths. The second segment consists of 14 miles between Sorn and Annbank, also primarily off-road with some road sections. The final 9 miles from Annbank to Ayr are contested on road and tarmac paths. Some parts of the route may be muddy or involve difficult terrain.

The event provides support through checkpoints situated every 10 miles, offering fruit, snacks, and cold drinks. Water stations are also placed every 5 miles. Runners can utilize a drop-bag service for checkpoints and a rucksack transport service to the finish line. Facilities at the Riverside Stadium include designated changing rooms and showers. Transport options are available from Ayr or Kilmarnock to the start line for a fee. The overall time limit to complete the course is 10 hours.
