INDIANAPOLIS -- Carb Day practice at Indianapolis Motor Speedway is just one hour out of an available 40 hours of track time in the lead-up to the 100th running of the Indianapolis 500 (Sunday 11 a.m. ET, ABC, WatchESPN and the ESPN app).
But as the last time the 33 cars and drivers are on the track prior to the biggest race of the year, teams take that last hour very seriously. That was especially applicable this year, because Carb Day featured the hottest temperatures so far during the Month of May: more importantly, the kind of hot, humid conditions that are expected on race day.
