2018 Trail Series

Discover the trail runner in you this spring, summer and fall. The Fleet Feet Sacramento Trail Series takes your running off-road with a three-part series of sell-out races that promise to deliver breath-taking wilderness locations within a 1-hour drive of Sacramento.

The series kicks off with The Dirty Secret Trail Run in May, followed by the Blood, Sweat and Beers Trail Run in July and wraps up with Granite Head Trails & Ales in October. Each of the three races in the series offers a Short Course and Long Course distance to choose from.

Enter the whole series or choose the race that suits you. If you tackle all three you will save some green (10%) and receive an awesome trail series trucker hat (ready for unveiling soon) for being so adventurous. We keep track of your finishes so at the third race you can pick up your trucker hat.

Course Information

Stream crossings, foot bridges, and baby heads what do they all have on common? You will find them all out on course at the Dirty Secret Trail Run. OK we don’t mean literally seeing baby heads, but you will come across Baby Head Alley named after the rocks that line the trail that look like (yes you guessed it) baby heads. Knickerbocker Creek crossing is something that can’t be missed just after 3 miles on both courses and one of the highlights of the run. Both races start from Northside Elementary School in Cool, CA. Be one of the first to explore this all new course complete with butterflies, newts, rolling hills, and plenty of dirt. This course is perfect for the first time trail runner while also still challenging enough for the trail vets. The long course is 10.3 miles and the short course is 5.8 miles. Courses and distances are subject to change.

Aids Stations (feature water and nuun electrolyte replacement drink)
Mile 1.34
