Similar to what Brent said. Definitely different type of race. Lots of strategy involved. Lots of fuel to burn off in the beginning and tire conservation. With 75 gallons of fuel in the beginning they are slower, but as that burns off the faster they get. The last 25-30 laps is when you’ll most likely see the fastest times and cars making moves. Nothing like the big rumble of those cars. You need to experience at least a couple in person before you make up your mind. Make sure you go thru the tunnel into the infield and hang out in one of the turns for qualifying or practice. Awesome experience
