This is the transferred participant list from the 2022 February Glentress event

The event is part of a fantastic weekend of trail races with the Glentress 21k & 10k Trail Races scheduled for the Saturday.

A trail marathon event based in the beautiful Scottish Borders. Glentress Forest is described as the 'Gateway to the Tweed Valley Forest Park'. Perhaps more renowned for its mountain biking, Glentress also offers a superb array of forest trails, making it a fantastic location for trail running. The area features mile upon mile of waymarked trails including forest walks, woodland singletrack and heather clad moorland. A great way to explore all the unique aspects of this stunning forest.

Event Briefing Notes

Situated between the small Borders towns of Peebles and Innerleithen & just one hour away from Edinburgh, the location is second to none.

Participant Feedback


“Today's Glentress Marathon was definitely the most brutal race ever but I would like to say a huge thank you for a very well signposted route and to all the marshals and photographer for hanging about for me to come in. It really is appreciated as the last marathon runner to feel like i am as important as the first one finished” Caroline Ness

Course: The 42km route comprises two 21km circuits starting & finishing at the Glentress Peel visitor centre. Utilising a fantastic variety of terrain from hard packed gravel trails to twisting forest singletrack...not to mention a challenging climb on the Black graded MTB route...this amazing course ofers something for everyone.

This is a great event to bring along family & friends with the route returning back through the finish area at the half way point, there's plenty of opportunity to offer encouragement.


Route Highlights: Starting & finishing at the Peel Centre trailhead the route features sections of the waymarked walking trails including the Glen Trail alongside Glentress Burn, linking in with Buzzard’s Nest Trail, which winds through the magnificent Douglas firs. Then it's onto the Time Trail which passes the fortified iron age settlements, with spectacular views over the Tweed Valley & the Caddon Hills.


The route then explores further into the more remote parts of the forest incorporating sections of the Tower Trail & the Black graded mtb route, climbing high to the top of Glentress Forest, offering some stunning panoramic  viewpoints.


A spectacular singletrack section leads across the heather clad moorland before descending back into the forest eventually rejoining the Buzzard's Nest Trail to finish with an exhillirating descent back at the Peel Centre trailhead.


Total Ascent 42k:  1,500m/4,920'     

21k Circuit:  750m/2,460'        

The 42k is two circuits of the 21k route.

Terrain: The course incorporates sections of the Tower Trail & Black mtb trail which include several long and continuous steep slopes for over 500m. There's a great variety of forest singletrack, a few sections of open moorland & awesome singletrack.

Please note: Sections of this route are on the black MTB trail 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.

GPS Measurement: We try to ensure that we measure the courses as accurately as possible using a number of different recording devices & various recording settings. Please note that the actual distance and elevation gain can vary between +/- 5 % depending on the measurement method, i.e. make & model of watch/GPS unit, unit settings, tree cover, etc. 

Time Limit: There will be an intermediate cut off time of 4hrs for the first lap and an overall time limit of 8hrs30 for the full event. (Based upon an average speed of 3mph/5km/hr). Anyone timed out after the first lap will still get a finish time for the 21k distance.


 Hydration/Feed Stations: These will be located at:

Description                              Distance
1.   Shieldgreen Tower:            11/32km                   Hydration/Feed Station (jellies, bananas, mixed fruit & nuts)
2.  Soonhope Craig:                 17/38km                  Water only will be available here located in containers.

In addition, if you'd like some of your favourite nutrition without having to carry it for the full duration participants will be able to leave any personal nutrition here.

Please Note: Previously, due to ice & snow on the trails we have needed to relocate the aid station &/or 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. To help minimize waste you will need to bring your own water bottle, bladder, etc.
