Redwood (Spring) Trail Run

Embark on an unforgettable trail running adventure at the Redwood (Spring) Trail Run on Saturday, March 21, 2026, in the majestic Redwood Regional Park in Oakland, CA. This event offers a challenging yet incredibly scenic experience for runners across a range of distances, including a 50K, Marathon (26.2M), 30K, Half Marathon (13.1M), and 5 Mile race. Starting and finishing at the Chabot Space & Science Center, participants will delve into a course renowned for its breathtaking beauty, featuring towering redwoods, sweeping ridge views, and tranquil streams along the East Ridge, West Ridge, Stream, and Bridle trails.

The course is a dynamic mix of single-track paths and dirt roads, presenting varied terrain with big hills, rolling sections, flats, and exhilarating downhills. For instance, the Half Marathon includes an elevation gain of 1,530 feet, while the Marathon climbs 3,070 feet, and the 50K features a robust 3,550 feet of gain. Runners consistently praise the excellent course markings, which include color-coded ribbons and distinctive polka-dot flagging at turns, ensuring a clear path through the verdant landscape. Typical race day conditions in late March offer pleasant highs around 65°F and lows around 49°F, with a minimal 13% chance of precipitation, providing ideal weather for tackling the trails.

Aid stations are strategically placed approximately every 5 to 6 miles, fully stocked with fresh fruit, salty snacks, candy, water, and Skratch electrolyte drink to keep you fueled. It is recommended that runners carry at least 20 ounces of water between stations, especially given that the event is cupless in an effort to reduce waste. Finishers will be celebrated with a custom medal, and 50K participants will also receive a unique custom coaster, with event t-shirts guaranteed for pre-registered runners. Whether you're seeking to push your limits on challenging climbs or simply immerse yourself in the serene beauty of the redwood groves, this race promises a rewarding experience.
