Long and Short fat bike UP fun!

Groomed by NMMBA, the long and short races will have separate groomed courses that overlap within Timber Ridge at the start/finish line to record each lap. The short race loop at nearly 2 miles in length, will approximate the previous years courses. The long race loop will be close to 4 miles and use some of the Timber Ridge groomed trail and some of the NMMBA groomed trail. Each race will have racers putting in as many laps as possible in 90 minutes for the Long race and 45 minutes for the Short's race. Come by the start/finish at 1:29:59, and you can keep going! Come by at 1:30:00, and you're done. Register by Valentine's Day to get a personalized race plate with your name!
