The Reservoir Dogs Trail Run is an October trail race held at San Pablo Reservoir, located near Orinda in the East Bay. All race distances commence and conclude at the San Pablo Reservoir Visitor Center. Participants can select from 5K, 10K, half marathon, or 35K distances. The event has a participant cap of approximately 300 individuals across all races. Inside Trail Racing organizes this event. The longer distances feature a 6.5-hour time limit, maintaining the structure of a genuine trail race as opposed to a casual reservoir run. The course's distinctive feature is its complete circuit around Briones Reservoir using EBMUD trails, incorporating segments typically accessible only with permits. Expect a mix of moderately technical dirt paths, open fire roads, undulating hills, wooded single-track, winding single and double-track sections, exposed ridgelines, and expansive vistas of the watershed. The 10K, half marathon, and 35K races involve less elevation gain compared to many other Inside Trail events, allowing for faster times while still providing road runners with a true trail challenge. Aid stations are equipped with gels, trail mix, salty snacks, fruit, Coke, and Stroopwafels; however, participants must carry their own water between stations. Finishers receive a tech shirt and a medal, age-group victors are awarded trophies, and one participant receives the unique "Dead Last Finisher" award. Notably, dogs are prohibited despite the race's name.
