Mountain Bike! Orange County
by David Womack (Menasha Ridge Press)
Ride out the Irvine Haul Road and then attack the intervals on Loma Ridge—steep, steeper, and steepest. The hard work is finished after 4 miles, so drop down to Bolero Springs and then follow Limestone Canyon to The Sinks. A quick climb up Cactus Canyon takes you to Limestone Ridge. Ride the length of the ridge, eventually dropping back down to Limestone Canyon. A short jaunt on a fire road completes the loop.
