The frontstretch and backstretch were swapped, and the configuration of the track was changed from oval to quad-oval, with a new official length of 1.540 mi (2.478 km) where before it was 1.522 mi (2.449 km). The project made the track one of the fastest on the NASCAR circuit.

One of the oldest stops on the NASCAR circuit, the Atlanta Motor Speedway, held its first race on this day in 1960. A crowd of 25,000 watched Glenn “Fireball” Roberts ride to victory lane. The racetrack was built in the wake of the first running of the Daytona 500 in 1959.

When the Champions Grandstand was built, the start/finish line was moved from the west to the east side of the track, and two doglegs were added to the frontstretch to form a 1.54-mile quad-oval, which replaced the original oval.

How many laps is the Cup race at Atlanta? The Quaker 400 is 260 laps around the 1.54-mile track for a total of 400.4 miles. The race will feature three segments (laps per stage) - Stage 1: 60 laps; Stage 2: 100 laps; Stage 3: 100 laps.

Before the concept of speedway racing emerged, motorcycle races were held on dirt or cinder ovals or tracks, which were often called motordromes. The term “speedway” was first used in the 1920s to refer to these oval tracks specifically designed for high-speed motorcycle racing.

Speedway is popular in Central and Northern Europe and to a lesser extent in Australia and North America. A variant of track racing, speedway is administered internationally by the Fédération Internationale de Motocyclisme (FIM).

The World Championship of Speedway was staged at Wembley Stadium, London from 1936 to 1960. A post war boom came to an end in the early 1950s thanks to television and Entertainment Tax but a revival with the advent of the Provincial League in 1960 has been largely sustained ever since.
