Grand Ridge Trail Runs 5 Mile | Half | Full | 50K
November 8, 2025 @ 7:45 am - 4:30 pm PST
An event every year that begins at 7:45 am on day second of November, repeating until November 15, 2025
Join us for a trail run at Grand Ridge Regional Park, just across I-90 from Tiger Mountain. A great trail system awaits.
Grand Ridge is our Series Awards finale.
The aid stations are fully stocked with water, Nuun, Clif product, PBJ sandwiches, fruit, cookies, crackers and pretzels. As always, at the finish there will be a full variety of post race foods awaiting you.
This is a cupless race. All runners should carry with them a refillable container that they can run with. There will be a limited number of cups for emergency situations.
As part of our new Woodland Speeders program, we offer free kid’s races at all of our events. Parents are welcome to run with their kids. You can register your child during the registration process for your own race or sign them up later.
The trails will be open to other users during the event, including hikers and cyclists. This area is especially popular with mountain bikers so be alert! Please be courteous! Where the trails are narrow, please let other participants pass you if they want to get by. It is a passing runner’s job to tell the person in front that they wish to pass.
