Eli Lilly & Co. is taking its Vision Racing Wellness Tour on another lap around the racing circuit, offering fans free diabetes screening.

The campaign, in its second year, partners Lilly with Vision Racing, a team that competes in the Indy Racing League, whose races include the Indianapolis 500. Drivers Ed Carpenter and Ryan Hunter-Reay will serve as “ambassadors” for the tour, which offered diabetes screenings at the Indianapolis Motor Speedway through May before moving on to races in West Allis, WI, Fort Worth, Texas, Newton IA, Richmond, VA and Lexington, Ohio. Lilly diabetes products include Byetta, Humulin, Humalog and Glucagon.
