MOUNTAIN BIKE RACE SERIES 2026

The Kelso Mountain Bike Race Series begins May 5, and races run once a week until August 25, 2026. With 12 races, a finale event to cap our season, some incredible terrain, and multiple distances/categories, this is a great addition to your training program or a fun way to challenge yourself to achieve a personal best. Sign up for the series (12 races + finale event) and choose to race as many as you want. Or sign up for individual races and join us whenever it works with your schedule. We encourage everyone to sign up for the entire series as it includes access to all races and a limited edition 2026 MTB Race Series T-Shirt.

The popular Cyclocross Race Series also returns this fall to Kelso Conservation Area with 8 races, new courses, and as always – the thrill of racing under the lights! Races begin on September 8 and run once a week on Tuesday evenings until October 27, 2026.
