Flagstaff - Boulder, CO

The skyline of Boulder is dominated by the Flatirons; a series of almost vertical stone faces that frame the southwest skyline, and provide the typical background for the typical Boulder postcards. They also hide one of my favorite rides, which we simply refer to as "Flagstaff."

The ride runs up Flagstaff Road, which is what Baseline Road turns into once it runs past Chautauqua Park. The defining features of the ride are the amazing views of Boulder, the numerous switchbacks, and the sudden increase in grade around mile 4. The road also houses one of the best restaurants I've ever eaten at; the Flagstaff House. We like this ride because it's quickly accessible from downtown, and is a great workout that can be done in about 45 minutes. We often pair this ride with 4 Mile or the NCAR climb if we want to do something longer.

During rush hour, traffic up the road is fairly heavy, but there is a wide shoulder and because it's Boulder, everyone is usually aware and cautious of the bikers. However, because of its views, the road is also a drawing point for a lot out newcomers and out of town folks, who either have never seen a biker before and don't know what to do, or are so amazed by the random deer that they neglect to pay attention. Either way, caution is advised, especially on the switchback turns and the descent.

Distance: 6.30 miles to summit (intersection of Flagstaff Road and Bison Drive), 12.60 miles round trip.

Directions: Starting at 9th Street and Pearl, take 9th south, climbing up the Hill towards the Flatirons. At Baseline Road take a right. Baseline will turn into Flagstaff Road, winding up above the Flatirons. We usually turn at the intersection with Bison Drive, but the road continues for another couple of miles before ending near Gross Reservoir.
