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.
Total Ascent 10k: 393m
High Point of Course: 508m
Terrain: A great combination of woodland singletrack & forest roads, sections of the blue & red mtb trails.
Please note: Sections of this route are on MTB trails which the Forestry Commission have given permission to use for the duration of the race. However we do not advise you to run this at other times when mountain bikes will be using the trail.

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.
