The Great Buckeye Challenge – located at the beautiful Buck Creek State Park in Springfield, Ohio. With the new location in 2008 at Buck Creek State Park, the Great Buckeye Challenge enjoyed some major upgrades to the bike and run courses. The sprint course will feature an opening 1000 meter rectangle swim along the beach, a 20k loop bike course and an out and back run course on a gently rolling bike trail. The mini course will feature the same 1000 meter swim course followed by a 40k loop bike course (same course as the Wheelie Fun Series used in 2005) and finishing with an out and back 10k run on the bike trail. The half distance race features a two lap swim, followed by a two lap – 28 mile rolling bike course and finishing with a two-lap out and back run on the bike trail.
