Spacerock Trail Race

SPACEROCK Trail Race : Vasquez Rocks Natural Area Park, October 17, 2026

The SPACEROCK Trail Race is a trail running event held at Vasquez Rocks Natural Area Park in Agua Dulce, California. The park features distinctive rock formations and canyons. Trails include packed dirt, sandy creek beds, rocky sections, boulders, and single-track segments.

Multiple race distances are offered as full loops:

• Half Marathon+ (about 13.9 miles, listed as just under 14 miles)
• 15K (about 14.3 kilometers)
• 10K
• 5K

The Half Marathon+ course is described with substantial elevation change, with over 3200 feet of total ascent and descent. The 15K route includes extended single-track sections and steep climbing in places. Both the 15K and Half Marathon+ courses pass through a dark tunnel section referred to as the black hole tunnel, which is reported to be over 500 feet long.

Course support includes a network of aid stations positioned on the course. Five aid stations are listed overall; depending on the distance, runners encounter between two and six stations. Stations provide water, electrolyte products, energy gels and chews, salt capsules, and snacks. The event operates as a cupless race at aid stations, so runners should plan to use a personal collapsible cup, water bottle, or hydration pack to refill at the stations.

Participant items listed for finishers include a collectible finisher medal, race shirt, finisher certificate, event photos, and finish line food and water. The event is organized by New Global Adventures and takes place inside Vasquez Rocks Natural Area Park. Visit the organization's website for the most recent information.
