Like Unchained said, Blarney Island! I run there every week. Its a blast. Its not sanctioned, and not timed. Its like street racing on the water. We do have all the safety and everything like the rest of the races, dive teams, recovery boats etc. We run back to back, and you cant pull your boat out of the water, or even make changes between rounds. Its truly run what you brung. If your ever in the Chicagoland area over the summer, come check it out!
