Route Description:

Starting from the Glentress Peel visitor centre the intitial section features parts of the waymarked walking trails. Click HERE for details 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 offering superb views across the valley high above Peebles.

A great undulating singletrack through the tall pines leads onto a more continous climb up to Soonhope Craig. The forest opens up here with fantastic panoramic views as the trail winds it's way up the heather clad hillside.

A section following the Tower walking trail gives a brief descent into the forest before a continuous 'roller coaster' section of singletrack weaves along the slopes of Middle Hill. A series of switchbacks climbs high to the upper reaches of Glentress Forest, offering more great views.

The high point of the course is reached at the mast at Dunslair Heights (600m). Enjoy a well deserved refreshment stop here & relish the thought that most of the climbing is done now & it's now time to get the adrenaline going on the exhilarating descent of the Black graded mtb trail...

The course rejoins the forest road soon after 'Leithen Door', following the forest roads for a few kilometres before rejoining the Buzzard's Nest Trail. Finish with another exhilarating descent back to the Peel Centre trailhead...

We've experienced some fantastic winter conditions at Glentress at the previous events. The weather can change quickly or vary, with conditions in the valley very different from high up in the forest.To ensure you're prepared for the conditions that can be encountered at this time of year, all participants must dress appropriately for the conditions with suitable clothing & footwear.

Equipment List HERE. Please note this is mandatory for 21k participants.


Hydration/Feed Station: This will be located at:


Mast/Dunslair Heights:   11km   (water/juice, jellies, bananas, mixed fruit & nuts are provided)

See course map for specific location.

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.
