Course Description

One of the most hallowed races in the western US. Held the day before the real ‘Queen of the Classics’, the French race that goes from Paris to Roubaix.

An 18.7 miles (30k) loop with 43% paved roads & 57% unpaved roads in North Boulder County. Rolling terrain on roads that can be anywhere from smooth to extremely rutted. It all depends on the weather running up to the race. If it is wet on race day, expect slippery, sloppy conditions on the dirt sections. Neutral support is based on volunteer availability and is unlikely. Please bring a pump and spare tube. Do a “bolt check” and bottle cage press.
