The SPACEROCK Trail Race returns to Agua Dulce in California on October 17th, 2026. This event offers a unique trail running experience with distances for runners of all levels—5K, 10K, 15K, and the half marathon.
Race morning finds participants gathering at the world-famous Vasquez Rocks Natural Park. The park's rugged trails and stunning rock formations provide an out-of-this-world setting. As you make your way through this challenging terrain, keep an eye on the sky—on race day in October, temperatures typically range from 14 to 26 degrees Celsius, with a comfortable average of around 20 degrees.
The SPACEROCK Trail Race has been running for several years now and continues to grow. With thousands of participants annually, this event is more than just a race; it's an opportunity to explore the exotic trails that have featured in numerous TV shows and movies. The proceeds support local community scholarships and contribute significantly to Agua Dulce’s trail development projects.
The course venue offers diverse terrain with technical sections that challenge even seasoned runners. Participants will experience both uphill climbs and downhill descents, all on a well-maintained dirt surface. Notable features include the iconic rock formations that serve as landmarks throughout the race.
At the start of the event, runners will gather at the designated area within Vasquez Rocks Natural Park. The course layout includes aid stations strategically placed to ensure hydration and nutrition needs are met. A slight elevation gain is expected, but this adds to the overall enjoyment and challenge of the trail. Additionally, special attention should be given to the weather conditions on race day—light winds and low humidity make for comfortable running.
