The Iowa Coalition of Off-Road Riders (ICORR) is a volunteer-based organization formed in 1990 with the mission to promote, preserve, and improve mountain bike trail access Iowa. Today, ICORR is a non-profit 501 (c)(3) organization dedicated to building and maintaining sustainable mountain biking trails in the Coralville/Iowa City area.
ICORR maintains the Sugar Bottom trail system on the edge of Coralville Reservoir under contract with the land owner, the US Army Corps of Engineers Rock Island District. ICORR also partners with the City of Coralville to develop and maintain off-road trails throughout the city including the Woodpecker Singletrack trail system.
The use of the trails is free to all but please consider volunteering, giving a donation, and/or joining ICORR.
