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 Indianapolis-based Lilly with Vision Racing, a racing 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 will offer diabetes screenings with A1c testing and risk factor assessment in addition to blood pressure and cholesterol screening through May at the Indianapolis Motor Speedway before moving on to races in West Allis, WI; Fort Worth, Texas; Newton, IA; Richmond, VA and Lexington, Ohio.

Lilly VP and chief marketing officer Rob Brown called it: “a great opportunity to bring a truly unique health offering to the track. In select cities, IndyCar race fans will have access to a certified diabetes educator in addition to the diabetes screenings at the Wellness Tour. Through these offerings, Lilly hopes to help people stay on track with their health.”

Lilly diabetes products include Byetta, Humulin, Humalog and Glucagon.
