The Boulder Skyline Traverse is an ~18 mile trail route that covers the 5 peaks of Boulder (South Boulder Peak, Bear Peak, Green Mountain, Flagstaff Mountain, and Mt. Sanitas). You'll gain roughly 5,000 ft of vert! This is a challenging intermediate-to-advanced route, best suited for runners with strong endurance and prior trail running experience. Transportation will cut off at 1pm. RSVP by October 17th. We are limiting this year's traverse to 100 people, so sign up before it's closed!
