Situated between the small Borders towns of Peebles and Innerleithen & just one hour away from Edinburgh, the location is second to none. Perhaps more renowned for its mountain biking, Glentress also offers a superb array of forest trails, making it a fantastic location for trail running.

Climbing to the high point of Glentress Forest on the 21k

10k Course:                  "Tough Route with Stunning Views"


The new course climbs 'slightly' higher than previously but the breathtaking views & thrilling descents are certainly worth the effort. With nearly 400m of ascent packed into the initial 6k, this will be quite a challenge!


We've added sections of the blue mtb trails which gradually wind their way up through the forest, leading to the infamous 'Spooky Wood' climb with it's numerous switchbacks. Topping out at 480m, reaching 'The High Point' of the course will be a leg & lung burner, but it’s well worth the effort as the hard climbing is completed now.


Savour the stunning views of the Tweed Valley, grab a drink at the strategically positioned 'Spooky Wood' hydration station & enjoy the fantastic sections of descent to the finish.

Hydration Stations:  There will be two hydration stations on the 21k and one on the 10k route. These will be at:

1. Spooky Wood: Both the 21k & 10k courses, located at the start of Spooky Wood climb at approx. 6k distance.

2. Tower Rig: 21k course, situated soon after the start of the 'Switchbacks' climb at 12k.

Check out the course maps to view these locations.

Please Note: Previously, due to ice & snow on the trails we have needed to relocate the aid station as the water has frozen in the containers. If conditions dictate there will either not be an aid station on the course or it will be at a different location. It is important therefore that you don’t rely on the aid station as your only source of nutrition/hydration. Ensure you carry sufficient personal nutrition & drinks with you for the full route. No cups will be provided. To help minimize waste you will need to bring your own water bottle, bladder, etc.
