10+ Longest NASCAR Racetracks

Before we begin looking at the longest NASCAR racetracks, it is useful to know how NASCAR measures them. Officially, it measures track length from the point 15 feet in from the outside wall. This means that at many tracks the drivers are traveling a shorter distance than advertised (but not by much). Here are the longest.

Talladega is the longest racetrack on the NASCAR Sprint Cup schedule. This 2.66-mile high-banked oval is one of two racetracks on the circuit that requires the use of restrictor plates to keep the speeds under control. Without the plates to limit horsepower, a Sprint Cup car could reach speeds here around 235 miles per hour.

Talladega opened in 1969 amid controversy as the drivers boycotted the race because of the extremely high speeds. Even in 1969, qualifying laps were averaging more than 199 mph.

Daytona International Speedway is the other racetrack (along with Talladega) that requires cars to use the horsepower-limiting restrictor plates. As a result, this 2.5-mile high-banked tri-oval features average speeds much slower than would be otherwise possible.

The qualifying record is more than 210 mph, but that was set in 1987, the last year before restrictor plates were mandatory. Since the restrictor plates have been implemented, qualifying speeds have been around 189 mph.

Tied with Daytona and Pocono at 2.5 miles, Indianapolis Motor Speedway is one of the great icons in all of motor sports.

This track is relatively flat with just 9 degrees of banking in the corners so drivers are on the brakes at the end of the two long straights. This keeps speeds reasonable (the qualifying record is a little over 186 mph).

Pocono Raceway

Pocono Raceway is the last of the three 2.5-mile tracks and bills itself as "The Superspeedway That Drives Like a Road Course." The triangle-shaped track has three different corner lengths and bankings, making it very difficult to set up a car and to drive well. Pocono is, in a word, unique.

That distinct shape and challenging setup has kept speeds down. While drivers can top out at more than 200 mph at the end of the front straight, the qualifying record is just 172.533 mph.

Watkins Glen is the longer of the two road courses on the NASCAR Sprint Cup schedule. The "short course" portion of this New York State racetrack that NASCAR uses measures 2.45 miles.

This is a twisty, challenging road course. The front stretch is a downhill plunge to a hard right-hander. Shortly after that, the drivers charge uphill through a series of esses and out onto the long backstretch. Drivers have to work hard for every inch of the 2.45-mile laps there.

Michigan is the older of the two NASCAR Sprint Cup 2.0 mile D-shaped ovals. Cale Yarborough won the first Sprint Cup race here in 1969.

Michigan features three different grooves in the corners, which bank at 18 degrees. Wide and fast, this track can make great racing, or it can make a good race to nap through. The wide track also keeps the number of cautions down, which sometimes allows the leaders to get away from the pack.

California Speedway was modeled after its Michigan twin. California is also fast and wide but features slightly less banking in the turns with only 14 degrees.

California opened in 1997 and has seen a number of fuel mileage battles as the fast, wide racing surface limits the number of cautions.

By way of comparison between the two 2-mile "D" ovals, California's qualifying record is just a bit over 188 mph, whereas Michigan's is more than 194 mph.

Infineon Raceway

Infineon Raceway is the shorter of the two road courses on the NASCAR Sprint Cup schedule. Originally it measured 2.52 miles, but the track layout has changed over the years. Recent events have been on the modified 1.99-mile winding, hilly road course.

The tight corners and dramatic elevation changes keep the speeds down there. The qualifying record is just over a 94 mph average for one lap.

Atlanta Motor Speedway

Although ninth on this list, Atlanta Motor Speedway is the fastest track on the NASCAR Sprint Cup Schedule. The qualifying record here was set by Geoffrey Bodine at 197.478 mph.

Originally Atlanta was a 1.5-mile true oval. However, in 1997 the track was flipped and a quad-oval was added to the front stretch, which bumped the official distance up to the current 1.54-mile length.

Six Tracks Tied at 1.5 Miles

Last on our list are the six different tracks on the NASCAR Sprint Cup schedule that all measure exactly 1.5 miles around: Chicagoland Speedway, Homestead-Miami Speedway, Kansas Speedway, Las Vegas Motor Speedway, Charlotte Motor Speedway, and Texas Motor Speedway.

More than a quarter of all racetracks on the schedule measure exactly 1.5 miles, making this by far the most popular racetrack size on the circuit.
