The Sierra Cup Mountain Bike Racing Series returns to USA Cycling sanctioning for 2015 to assist in providing qualifying opportunities for riders in the region that would like to race at Mountain Bike Nationals in Mammoth. The series will be the USA Cycling Regional Championship for Northern California and Nevada. 
Series points winners in each of the 23 categories will receive Regional Championship medals. All of the races have been in the series previously, although some are run by separate promoters.
The series kicked off May 2 with the Nevada City Dirt Classic #1 just outside of Nevada City. The Pine Nut Cracker continued to be a favorite on May 16 in Gardnerville. Ridin’ High at the Ranch on May 30 treated riders to the fun, flowy singletrack of Susanville Ranch Park in Susanville. The Kirkwood Mountain Classic at Kirkwood Resort on July 12 will give riders one last high altitude training opportunity before this year’s Nationals at Mammoth. The series final – the Great Tahoe Flume Race on August 23 – will run as a qualifier for the 2016 Nationals, and features fabulous trails and views above Tahoe.
