Embark on an exhilarating adventure at the Wild Goose Chase Lime Ridge 5K and 10K, set to challenge runners on February 21, 2026, in the scenic Lime Ridge Open Space of Walnut Creek, CA.

While specific aid station details are not provided, post-race treats await all finishers, providing a well-deserved reward after conquering the trails.

With typical race day conditions boasting highs around 65F and lows around 44F, and only a 15% chance of precipitation, February promises ideal weather for trail running in this picturesque open space.
