The Iowa Coalition of Off-Road Riders (ICORR) is a volunteer-based, non-profit organization formed to promote, preserve, and improve mountain bike trail access in Iowa.

ICORR needs to log 600 volunteer hours of trail work and 200 volunteer hours of patrol each year to keep the Sugar Bottom trails open for bikes. This is under a contract with the land owner: The US Army Corps of Enginners, which is signed each year.
