Reservoir Dogs Trail Run - Orinda, CA

Reservoir Dogs Trail Run : San Pablo Reservoir Visitor Center

The Reservoir Dogs Trail Run on October 10, 2026 includes multiple trail distances and is hosted at the San Pablo Reservoir Visitor Center on East Bay Municipal Utility District (EBMUD) land. Distances offered include:

• 5K
• 10K
• Half Marathon
• 35K

The course circumnavigates reservoir watershed lands and combines rolling fire roads, moderately technical dirt trails, and stretches of single-track. Hiking or trekking poles are permitted. Course markings use colored surveyor ribbon placed about every 200 meters, with heavy marking at turns; blue ribbons indicate wrong way. Laminated signs and flour arrows are used at complicated sections when allowed.

Aid stations supply a variety of food and drink items such as energy gels, chews, Stroop-Waffles, trail mix, chips, PB&J sandwiches, boiled salted potatoes, soda, water, and Skratch Labs hydration mix. Stations carry basic first aid items but not anti-inflammatory medicine. Runners are responsible for carrying their own water container because the event is cupless; reusable cups and 500 ml soft flasks are sold at the event. Disposable timing chips are attached to the back of each bib and official timing uses professional chip systems.

Additional logistics: capacity is 300 runners across all distances, there is a 6.5 hour time limit for the Half Marathon and 35K, parking at the boat launch has a $7 fee, and drop bag service is not available. All finishers receive a custom medal and top overall finishers receive custom trophies; age group awards are given by chip time. Visit the organization's website for the most recent information.
