The 100-mile route is the most challenging of all the routes as it has the distance and a significant climb. After passing through Downtown Denver, you'll ride west to Golden where you will climb Look Out Mountain.

As you descend into Morrison, you'll ride past Red Rocks, through Bear Creek Lake Park with its short but challenging climb up Mt. Carbon and continue south to Deer Creek Canyon. The course then turns back north and then east through Littleton and Englewood before heading due north back to Northfield.

If you are going to do this route, we recommend that you put some miles on your legs and do some climbing in the weeks prior to the ride. Ride be your first century ride ever!
