Spence Mountain Mayhem XC MTB Race

Please join Klamath Trails Alliance (race host) on June 7, 2025 at Spence Mountain for our first XC MTB Bike race. The race is sanctioned by OBRA and will require an OBRA License and an OBRA waiver.

KTA would like to encourage youth participation. For 2025 youths 18 and under can race free. All riders will still need a $5 OBRA license for insurance purposes. It is an add on or bring $5 cash to the event.

Courses include a 24 mile "long route" for advanced riders (Cat 1); 16 mile "medium route" for intermediates (Cat 2); and 10 mile "short route" for beginners (Cat 3). Advanced race starts at 9am; Intermediate race starts at 9:30am; Short route starts at 10am.

Local food truck (Heavenly Thai including vegetarian/vegan options) and local beer (Common Block Brewing) at the finish line. A custom race medal for the first 80 finishers.

It is important to sign up early so we can get an accurate count for prizes and meals. If you register on race day you may not get a meal, as the food truck has limited supply of ingredients.
