INTRO

South Mountain may be the most popular bike climb in the Phoenix area and the focus of professional cyclists such as South Mountain's KOM, Brandon McNulty and Phil Gaimon. There are at least two USAC races up South Mountain each year: the South Mountain Bike Classic in March, and the South Mountain Time Trial in May.  The first half of the climb consists of a softly winding road along a steep edge.

The average grade of 3.4% jumps to 4.8% when descent is removed form the gradient equation.  18% (one mile) is descent, 44% (2.4 miles) is at 0-5%, and 37% (2.1 miles) is at 5-10% grade.  The steepest quarter-mile is 8.9% and steepest mile 5.1%.

Traffic:  Minimal. Every last Sunday of the month is known as "Silent Sunday", and the entire climb is closed to automobiles.

Provisions:  None on the route. 

Weather: Average highs are around 104-106 degrees in the summer.  It gets hot out here so be sure to consult the PJAMM "Full Forecast" feature to assess what clothing and provisions to bring for the climb.

Great views at the top, but overall not that bad of a climb, lots of downhill interwoven into the steep pitches.

CLIMB SUMMARY

South Mountain (Affectionately called “somo”) is a favorite climb among Phoenix cyclists, right in the south Phoenix metro area about a 20 minute ride from downtown.

Definitely check out Holbert Lookout on the way up (closed to public)

Gentle winding turns = great place to practice descending skills!

Every last sunday of the month is “Silent Sunday”, a day where no cars are allowed on the summit road - only cyclists!

That’s a wrap!
