Iowa Coalition of Off-Road Riders
About ICORR
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 is a non-profit 501 (c)(3) organization dedicated to building and maintaining sustainable mountain biking trails at Sugar Bottom trails, and surrounding areas
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 Engineers, which is signed each year.
The use of the trails at Sugar Bottom is a privilege, please consider volunteering, giving a donation, and/or joining ICORR.
