It's no surprise that when an international bike race was being planned through Colorado that they included this very fun, very scenic ride in it. (The USA Pro Challenge 2013 bike race comes right through this little loop) Whether you take it from the east or west side, the views are spectacular, the climbs challenging, the downhills a total rush.

It can be hard to decide which vista to gape at. With Fort Collins and the eastern plains stretching into infinity on one side and Arthur's Rock, Horsetooth Rock and Horsetooth Reservoir on the other. Play it like a tennis match, looking from one to the other.
