It's Carb Day at the Indy 500, which means there'll be practicing, racing and, of course, Lynyrd Skynyrd.

Carb Day is short for "carburation day," which isn't a real thing anymore now that cars don't have carburetors, but the name sticks, and is a good excuse to race. It's also the last day of practice for racers in Sunday's main event.

Here's the schedule for the day's activities at the Indianapolis Motor Speedway:

10:30am - Q&A with INDYCAR Crew Members, Coke Stage, Plaza

10:45am - Firestone Pin Distribution, Pagoda Plaza

11am - Practice Begins

Noon - Firestone Indy Lights Pre-Race Begins

12:30 - Firestone Freedom 100

1:35 - IZOD Performance Pit Stop Challenge

3:30 - Miller Lite Carb Day Concert Begins, Lynyrd Skynyrd

The Freedom 100 is an Indy Lights Series race, and the Pit Stop Challenge is a way to watch pit crews see who is fastest in hopes of winning some prize money.
