Stevens Creek Striders Reservoir Run

The Stevens Creek Striders Reservoir Run returns to Cupertino, California on Saturday, September 12th, 2026, offering a variety of distances for runners and walkers alike. This event includes the Half Marathon at 13.2 miles, an 11K race, and a Lollipop Loop charity run/walk of approximately 2.5 miles. The race takes place around Stevens Creek Reservoir, featuring trails that wind through natural landscapes like Tony Look Park and Coyote Ridge.
On race morning in Cupertino, runners will face firm yet slightly soft trail conditions with moderate UV exposure typical for the region during September. Temperatures usually range from mild to warm, often requiring participants to dress accordingly as they navigate the challenging terrain of steep ascents and descents along the reservoir's perimeter. The event has been a staple of local running culture since its inception over four decades ago.
The Stevens Creek Striders have organized this race for more than 40 years, making it one of the longest-running trail races in California. In addition to attracting seasoned ultrarunners and trail enthusiasts, the Reservoir Run also serves as an introduction to off-road competition for road runners looking to explore new challenges. The event supports local scholarships through its Lollipop Loop charity run/walk.
The course for each distance varies significantly but all share common features such as aid stations stocked with essentials like water and energy gels at regular intervals along the route. For instance, the half marathon has four aid station stops spaced throughout the race while the 11K offers two crucial hydration points to keep runners hydrated and energized during their journey around Stevens Creek Reservoir.
Participants can expect trail conditions that are firm yet slightly soft underfoot with no significant precipitation risk expected on September 12th. The UV index will be moderate, suggesting the use of sunscreen for skin protection against sun damage throughout the day’s activities.
