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%).

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.

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.
