“A 4.5 mile sustained technical loop from Brainard Lake entrance through lesser seen wilderness.”— Kevin Stiffler
Sustained technical sections can make for a slower trail pace; there's certainly potential for hike-a-bike sections. Mind the weather at altitude.
Continue along North Sourdough for 1.2mi of fast, technical descending. Enjoy the breezy recovery of your descent because sustained technical climbing soon awaits.
After 1.2mi, turn Left onto South Saint Vrain Trail trail. Follow for 2.0mi and begin working through some of the most difficult climbing sections. Enjoy the babbling brook and dense forest here. Cross the stream and continue climbing to a mountain prairie. Keep your eyes open for wildlife in this wet prairie, but be sure to keep your tires on the narrow wooden bridges!
After 2.0mi, turn Left again onto a .5mi connecting trail towards Waldrop Trail, cross through some more wetlands and climb back into the forest. Shortly thereafter, you'll be greeted by some fast, flowy and smoothness on the Waldrop Trail for the final 1.5mi back to the Trailhead at the Brainard Lake Entrance Parking Lot.
This is a great addition to Sourdough Trail - Southern Half to increase difficulty and work on technical skills.
