It’s the perfect long ride for a modern road bike, covering cell-signal-free country with the security of aid stations and police traffic control. The shorter “Dall Sheep” course is an out and back of 31 miles, with a few punchy climbs and 100% tarmac goodness. While short on distance, this course is still huge on views and excellent, twisting, roads.
