This is Wisconsin’s Ultimate Lap! The Iron Bull Epic!
A 33 mile single track loop that combines the best of the old school with zippy machine built renovations. Ride past 4 lakes, 5 bermed boardwalks and 70 hills all the way to the Prairie Dells overlook and back.

Food, drink and Strava games to follow. Music by the Big Road Band. Pints to all finishers.
This event is held simultaneously with the Iron Bull Underdown Trail Races so you’ll get to party with those poor runners.
