Races summary
Here's what races are available for SPACEROCK Trail Race
Half Marathon
Route information
The SPACEROCK Trail Race features four distances, a Half Marathon, 15k, 10k & 5k race through the spectacular trails of Vasquez Rocks, PCT, and Agua Dulce trails.
This is a trail race that contains a good amount of physical challenge with elevation gains at 3250 ft for Half Marathon, 1,900 feet for the 15k, 1380 ft for 10k, and 650 ft for 5k runners. It is recommended that runners train for these elevation gains in the weeks leading up to the race.
The Half Marathon trail course consists of two separate loops, the orange loop, and the purple loop, these two combined create a slightly longer Half Marathon course at approximately 13.7 miles (22k) distance.
Going from the start half marathon runners will follow the orange course to the first aid station. From this point, half runners will take the LEFT fork to begin the purple course into the canyon section, then into the "black hole" tunnel. After coming out the tunnel half runners go RIGHT at the fork and follow the course trail markings guiding runners onto the challenging mountain section climbing three large peaks, passing two additional aid stations before returning to the PCT trail that heads back to the tunnel and returning to the first aid station to complete the purple course.
