When Charlie Kimball drives in an IndyCar race, as he will Sunday at the GoPro Grand Prix of Sonoma, he has a huge fan club rooting for him. When he joined Chip Ganassi Racing in 2011, Ganassi told him not to worry about winning while he learned the ropes from teammates Scott Dixon and Dario Franchitti. Novo Nordisk, which makes the insulin he uses and the insulin-delivery systems, has sponsored his car from the start. Kimball's father, Gordon, is a Stanford-educated engineer; he designed and engineered cars in the old CART series and Formula 1. Kimball was accepted at Stanford but deferred enrollment while he waited to see if his racing career would pan out. Saturday, World Challenge qualifying, 8:55 a.m.; USF2000 race No.
