I absolutely LOVE SPACEROCK. Watching the sun rise at Vasquez Rock to start an amazing and difficult half marathon course is addicting. I'll keep coming back. The vibe is out of this world.

I run a lot of obstacle courses and trail races. I highly recommend the SPACEROCK Trail Race. I drove up from San Diego, and the drive was worth it. Intimate, friendly atmosphere for the race. Stick around and “explore” after the race, you will be glad you did.

LANDMARK LOCATION

Experience running the exotic trails and sights of the world-famous Vasquez Rocks Natural Park in Southern California. Known as the backdrop from popular TV shows and movies, including Star Trek, The Flintstones, Battlestar Galactica, Planet of the Apes, and many classic western films. Now get a spectacular experience running the trails at the SPACEROCK Trail Race!

ALIEN LANDS

Vasquez Rocks features unique rock formations, canyons, and terrain that feels like you are running on an alien planet. The trails provide a variety of technical terrain, from packed dirt, sandy creek beds, rocks, and boulders as you traverse the course.

TOUGH COURSE

The 5K & 10K loop takes runners around the trails inside Vasquez Rocks with some moderate climbing and single-track trails. Ideal for first-timers, hikers, and those looking to elevate their trail running experience.

The 15K course provides a more intermediate to advanced runner challenge with a huge mountain climb, more single-track trails on PCT, and the black hole tunnel.

The Half Marathon+ course is considered one of the toughest in California with over 3200 feet of elevation gain & descent, and the total distance coming in just under 14 miles. A course that many trail runners consider an Ultra Half.

BLACK HOLE
