The Chequamegon Area Mountain Bike Association or CAMBA hosts the Seeley Big Fat Race this Saturday at noon on snow-covered trails east of Seeley. The race is for fat bikes only (tires 3.8 inches or wider). Courses are 6.5 or 22 miles. Online registration closes at 9 p.m. on Friday. CAMBA is raffling an OTSO Arctodus Fat Bike valued at just under $2,400, to fund grooming for over 70 miles of fat bike trails. Awards are at 4:30 p.m. Food and drink will be available at The Sawmill Saloon after the event.
