Sourdough Trail (North)

Trail Meter: 

The northern half of the Sourdough Trail puts hair on your chest, or umm, makes your legs more shapely and beautiful if you're a chick and a hairy chest is undesirable.  Big fat glacial boulders, twisty turny trail, rocks everywhere, and really choice mossy forest -- how could it get any better?  If you're jonesing for some technical rock work, Sourdough North has you covered.  Combine this trail with the new no-longer-in-wilderness South St Vrain Trail right next to Brainard Lake.

Sourdough North provides a challenging ride both directions, really, although the vast majority of sane folks prefer to go south to north (largely downhill, as shown in the elevation profile below).  Starting from the Red Rocks Trailhead, the rocky challenge begins almost immediately.  After a punishing mile or so, you start to hear the St. Vrain Creek ahead in the forest.  Take a pause on this gorgeous bridge crossing of St. Vrain Creek - a great reminder of why the Colorado high country is so dang badass!

Trail Meter: Fair»Good

From Beaver Res Rd. to South St. Vrain is fine. Maybe a few more rocks, so a few more good times.

West of 72 is open.

Trail condition updated to Poor.

Caught a bit of trail before a big storm moved in, it was moist and very good. After that it was flooded but afterwards looked on its way to good again.

Bone dry, no mud or snow

Sourdough from Peaceful Valley to SSV is in good shape. There's still snow drifts near the SSV/SD intersection but we busted most of them up so it's 98% rideable.

From redstonecyclery via Twitter: In case you were wondering, Sourdough/SSV loop is ON. #boco_trails #tuesnightride
