Redwood (Summer) Trail Run

Embark on an unforgettable trail adventure at the Redwood (Summer) Trail Run, set for Saturday, August 15, 2026, in the majestic Redwood Regional Park in Oakland, California. This cherished event, formerly known as the Cinderella Trail Run, offers a spectrum of distances from a challenging 50K and full marathon (26.2M) to 30K, half marathon (13.1M), 5M, and a 2M option for younger runners, ensuring a perfect fit for every trail enthusiast. Runners will traverse a meticulously measured course, confirmed by a Rolatape® surveyor's measuring wheel, through breathtaking landscapes, featuring spectacular views along the East Ridge and West Ridge trails, and winding paths beneath towering redwoods on the popular Stream and Bridle trails. Typical race day conditions in mid-August are ideal for running, with comfortable highs around 73°F and lows near 58°F, and virtually no chance of precipitation.

The course is known for its challenging terrain, featuring "quad-blasting uphills" and significant elevation gains across all distances, like the 50K boasting 3,548 feet of climb and the Marathon with 3,068 feet. Expect a mix of single-track and dirt roads, all clearly marked with ribbons and polka-dot flagging to guide your journey. Aid stations are regularly spaced every 5-6 miles, well-stocked with fresh fruit, salty snacks, assorted candy, water, and Skratch electrolyte sports drink to keep you fueled. In an effort to promote sustainability, this is a cupless race, so runners are encouraged to bring their own hydration vessels and are recommended to carry at least 20 ounces of water between aid stations. Remember to stay on the trails to avoid poison oak, a common plant in California parks.

The Redwood (Summer) Trail Run is celebrated for its stunning natural beauty and welcoming atmosphere, making it an excellent choice for both seasoned trail runners and those new to the sport. The start and finish lines are conveniently located at the Chabot Space & Science Center annex lot, offering free parking and drop bag facilities for longer distances. Upon crossing the finish line, participants receive a custom medal, with 50K finishers also earning a custom coaster. Reviews often praise the "amazing scenery" and the overall positive experience of running amidst the majestic redwood forests of Oakland.
