Gypsy Glen via Cardona Forest gets a second vote from me. It was really dry when a mate and I rode it yesterday. We then cut into Glntress via Jenny’s Brae before climbing up the Ho Chi Minh trail and dropping down secrets and lies (ask in the Hub bike shop for directions) onto the climb up from Deliverance. After that, we headed down the old natural trails that plummet you down pretty much straightline to the valley floor. Thet were riding particularly well yesterday but the final section in particular is not for the saddle up XC crowd.
Alternatively, you could ride up the walkers trails off the top of the red climb before the final fireroad push to Spooky Wood. This is a steep up and down trail which will take you to the mast. From there, head down the black until you reach the section of trail that takes you round the open quaried slope. There is a path which climbs up through the trees and takes you over to Lee Pen. Lovely natural trails with a short rocky tech fest off the top then it’s fast and open into Innerleithen. You can return by the riverbank trails.
Failing that, the Eildon Hills from Selkirk is considered a bit of a classic as is the Yarrowford, military road, minch moor, three brethren circuit. Loads to do!
Cheers
