Mountain bike racing returns to the famous Flume Trail above Lake Tahoe on Sept. 10.

The Great Tahoe Flume Race is presented by the Reno Wheelmen and sanctioned by USA Cycling. It is part of the Sierra Cup Regional Championship Series, a seven race point series to determine the best riders in Northern California and Nevada.

The race starts next to Spooner Lake in Lake Tahoe Nevada State Park at 9:30am. The course will take riders over 23 miles. The course has more than 3,300 feet of climbing and the entire course is above 7,000 feet.

There are age and ability categories for all levels of riders. All categories will complete the same course. All proceeds from the event go to supporting the all-volunteer backcountry patrol in the Lake Tahoe Nevada State Park. Celebrating its 10th year of service, the patrol provides directions, mechanical help, and medical assistance to all park users. It is an International Mountain Bicycling Association affiliated National Mountain Bike Patrol, and one of the largest chapters in the country.

Registration is online. The race is limited to the first 200 to sign up.
