The Reservoir Dogs Trail Run began as a unique opportunity to circumnavigate Briones Reservoir on trails not typically open to runners, drawing in over two hundred participants annually since its inception five years ago. The event supports local trail maintenance and community recreation programs through entry fees while providing an immersive experience of the East Bay’s natural landscapes.
The course begins at San Pablo Dam Road where runners will embark on a route that includes single-track paths and fire roads around Briones Reservoir, featuring rolling terrain with some steep ascents and descents. Aid stations are well-placed along the trail to provide necessary hydration and energy refills for longer distances such as the Half Marathon and 35K races.
Weather conditions in October generally feature mild temperatures ranging from a low of 12°C early morning to a high around midday, with an average humidity level ensuring runners stay hydrated. The sun will be out most of the day providing about nine hours of sunshine but UV index remains moderate at four, requiring some protection against exposure.
