NEW THIS YEAR, all routes begin at the South Gate of the Summerfest Grounds (intersection of Polk Street and Harbor Drive). Due to the extensive planning of this event, UPAF's Ride for the Arts, sponsored by Miller Lite, will not be rescheduled due to inclement weather. Registration on the day of the Ride begins at 6 a.m. Start times will be distinguished by the color of your rider number on your bib. Bike trailers will be allowed on all bike routes. All routes start at Summerfest. Each route is led by an official pace car.
