A great loop on the west side of Denver near the intersection of C-
470 and I-70. The loop starts with a decent climb, then follows the
ridge south on some sweet moderate technical singeltrack, crosses
over near Red Rocks and climbs back to the trailhead.

Meeting the Denver BOMB crew at 5:45 at the trailhead...leaving
Colorado Springs at about 4pm. Will be back to Colorado Springs by
9:30 - 10:00 'ish.

me know ASAP if you're interested (719) 964-3595.
