Created By:
With nearly 5,000-feet of climbing, this is one of the standard rides I do to gauge my fitness level. Rolling hills lead to gradual 12-mile climb which leads to shorter and steeper climbs before descending into Estes Park. Descend 20-miles into Lyons before rolling hills take you back to Boulder.
