Sourdough Trail (South)

Trail Meter: 
Good

Sourdough South is a rolly polly lungbuster, traveling north-south and paralleling (but nowhere near) the Peak to Peak Highway.  Solitude and suffering await you... ok, it's really not that bad if you're mentally prepared for high altitude riding with some loose rocks thrown in there.

You can start this trail from the south at the CU Research Center / Rainbow Lakes trailhead, and from the north at the Brainard Lake trailhead. If you cross Brainard Lake Road, then the Sourdough trail continues - we call that section Sourdough North because this section of trail has a pretty different character from Sourdough South.

Running well.

all good, enjoy!

The lower 4 miles were dry. I'm assuming the upper 2 miles were also dry.

Deep snow drifts from before Peace bridge to Brainard road.  Will need a few weeks to melt.

Snow

Rode there on 2/11. Snow was deep and soft, but centerline was mostly rideable. Ride on the fattest of fat bikes and you'll probably have a great time!

Snow

Open to fatbiking. Skinny tires need not apply.

recent floods created no significant damage... blowdowns are likely to be found because of saturated soils and winds. Snow is on the ground...
