The Chippewa Off Road Bike Association (CORBA) is a volunteer based organization dedicated to building, improving and promoting mountain bike and other singletrack-based opportunities in Wisconsin’s Chippewa Valley, including trail running, snowshoeing and hiking.

CORBA currently works with the Eau Claire Parks & County Forest Department, Friends of Hickory Ridge, the City of Altoona and the City of Eau Claire in its ongoing trail development mission.  The organization relies entirely on volunteer efforts and partner donations, and all membership dollars are returned to trail improvements.

Formed in 2005 to work with Eau Claire County on trail development at Lowes Creek County Park in Eau Claire, CORBA and its volunteers put in over 400 man-hours that year to build six miles of singletrack.  Also in 2005, CORBA helped host the first Chippewa Valley Firecracker mountain bike race, as part of the Wisconsin Off-Road Series.  In 2006, CORBA applied for and received non-profit status and is recognized as a 501(c)3 organization.

Since its inception, CORBA has played a hand in developing and maintaining shared-use trails at Lowes Creek County Park and Northwest Community Park in Eau Claire, Hickory Ridge in Chippewa County and Otter Creek in Altoona.  The Chippewa Valley Firecracker has grown to include a trail run and has become one of the largest and most popular races in the WORS series.  In 2011, the Chippewa Valley Powder Keg snowshoe and fat-bike race was added to CORBA’s event lineup.  The Fall Back Blast ultra trail run was added in 2014.  In 2015, CORBA hosted the US National Snowshoe Championships.
