Cycling Magnolia Drive
A beast of a climb out of Boulder, Colorado
Ride 4.5 miles gaining 2,185’ at 9.1% average grade.
Climb summary by PJAMM’s John Johnson.
The thing about Magnolia Road is that it hits you with a right cross on the chin as soon as you enter the ring -- after a few pedal strokes you’re at 11.8% average grade for a quarter-mile and 11% for the first mile (gaining a whopping 620' over that distance). The steepest stretch is 0.2 miles at mile 2.88-3.08 (16.4%).
There is plenty of parking at the beginning of the climb.
The first 9/10s of a mile are at 12.3% (it felt like more). . .
. . . be prepared!
This is a beautiful and scenic ride as can be seen from our YouTube playlist of the climb. We enter Roosevelt National Forest at 0.8 miles as we struggle with mid-teen grades just before the grade eases for a short bit at about the 0.9 mile mark. With the seventh highest average grade of the Top 100 climbs at 10%, this little devil will surely test your legs.
The climb and its grade can be followed on our YouTube video which uses Garmin Virb with grade and elevation overlays.
Traffic and Roadway Report: As of August 2014, the roadway surface was very good. While there is no shoulder on this road, there is not a lot of traffic either -- the road felt safe to ride.
The blessed finish -- that is one TOUGH road bike climb. 👍👍
