High Point

This newly designed, lengthened and demanding 16-mile loop runs clockwise this year with ~1,700′ of elevation gain per lap. The 4′-wide trail offers ample passing opportunities. Linking together the new Phillip S Miller Trails and the existing Ridgeline Open Space Trail System, this spectacular course offers panoramic views of the Rocky Mountains to the west and the town of Castle Rock below to the east. Fast punchy hills, green oak, and pinyon pine provide an exciting landscape to race through.

Marathon competitors will complete three loops, XC competitors race two, Appetizer one. The 3-person Relay Team racers ride one loop each. Juniors ride approximately 10-16 miles depending on age. Racers leave the start at the MAC and proceed over the new pedestrian bridge crossing Wolfsenberger Rd to the existing Ridgeline Course, then back again to the new Phillip S Miller Park trails.
