Dirty Secret Trail Run
A truly great trail is inspiring, has hidden secrets and plenty of challenges. The Fleet Feet Dirty Secret Trail Run has all of these features packed into two scenic course options: a Short Course; 5.8 miles and a Long Course; 10.3 miles.
Held on the trails in Cool, California, Dirty Secret is perfect for first timers and trail vets. Hard-core runners looking for places to test their endurance will find plenty of the trails challenging like "Baby Head Alley", a gnarly down hill with lots of twists and turns and you guessed it rocks the size of baby heads. There's no separate jogging lane but there is plenty of single track. Those new to the trails will have to own up to their true ability and seed themselves accordingly in the proper wave start. Be prepared for the typical trail obstacles of rocks and roots, some low tree branches, slopes that are alternately grueling and a demanding climb out of Knickerbocker Creek which is the backbone of both the long and short course.
