Race track for greyhounds is how long?

Answer 1

Greyhound tracks in the United States are uniformly a quarter of a mile in circumverance.

The most common race distance is 5/16 mile. This starts down in a chute that extends beyond the start of the home stretch.

The next most common distance is 3/8 (6/16th) of a mile. This starts near the far turn on the backstretch.

Other common distances are 7/16th and 3/16th, both of which start near the head of the backstretch.

Rarely, a 9/16 distance race is run, sometimes known as a "Super Marathon". It begins in the same place as the 5/16 race does, and the greyhounds make two full circuits.
