Held in conjunction with the Glentress 21k Trail Race & 10k Night Race on the Saturday


We are pleased to introduce Vera Maria as our event ambassador. You can follow Vera Maria on instagram & see how she is getting Ultra ready (& excited:) for this year's race. Vera will be sharing her training adventures & preparation for the event in the coming months with an emphasis on the fun side of running. Her main aims are to run a faster time as well as enjoy it! 

The Tweed Valley Forest Park is described as the main visitor attraction in the Scottish Borders. The park is made up of a number of forests each with their own unique character  "strung like pearls along the silver thread of the River Tweed". The area has a rich heritage of ancient forts, settlements and towers to explore.

We've designed this ultra as a journey through this unique landscape taking in spectacular panoramic views, extensive forests, across ancient drove roads & rolling hills and along beautiful riverside trails of the world renowned river Tweed.

Course Description: Both routes will start & finish at the Peel Centre Trailhead. The initial section climbs steadily through Glentress forest on the Buzzard’s & Time trails, offering panoramic views to the Caddon Hills looking down on the river Tweed winding through the valley below. A short descent through the forest leads onto the Tweed Valley Railway Path, a multi-user trail which links the towns of Innerleithen and Peebles. This follows along the banks of the Tweed to Cadrona village, followed by a short road section into Cardrona Forest. We’ve utilised some great sections of single track through Cadrona forest, initially following Kirk Burn before gently ascending the lower slopes of Pikes Knowe & Wallace’s Hill.

Heading along the Tweed Valley River trail

The next section leads to Traquair to join the Southern Upland Way (Scotland’s coast to coast route) & part of the ancient Cross Borders Drove Road. This track initially climbs up through the forest then to the open moorland of Minch Moor, the high point of the route at 520m

Soon after this point the two routes split, with the 50k descending through Traquair forest & the 65k continuing further on across the moorland terrain. It's worthwhile here to take in the spectacular panoramic views of the rolling hills & the river Tweed winding through the valley below.

The 65k route continues east on the Southern Upland Way which winds its way over the rolling hills to the Three Brethren Cairn followed by a superb descent through Yair Forest. A short road section leads to Traquair Forest then onto the riverside path at Walkerburn, re-joining the 50k route.

Enjoying a breather at Three Brethren Cairn

The 50k route descends through Traquair Forest to re-join the 65k near to the village of Walkerburn & linking back onto the riverside path. Pass Haugh Head Railway Bridge & cross the Tweed Bridge at Innerleithen to re-join the Tweed Valley Railway Path, returning through Cardrona village. The final section follows the route back through Glentress Forest to finish with an exhilarating descent back to the finish.
