Going to the United States Grand Prix at Circuit of the Americas

Hello! I’m going to my first race in Austin next month with my company and looking for some help on what race day, Sunday, will look like. Race officially starts at 1:00, but I’m looking for help on how soon before the race we should show up, how long does the race last, when the concert usually starts after the race, and how long the concert actually lasts? Trying to plan out the day and have no idea what to expect.

Also, any other hacks, tricks, or tips on how to get the best experience at COTA would be greatly appreciated!

Thanks!
