The proper length of the first lane of a competitive running track is 400 m (1,312.3 ft). Some tracks are not built to this specification, instead being a legacy to imperial distances such as 440 yd (402.336 m), equivalent to a quarter of a mile.
The 300 metres is an uncommon (meaning not on an Olympic or World Championship program) sprinting event in track and field competitions. The race starts on a straight and therefore comprises two straights and one bend.
The high school version uses a standard 45 meter start to the first hurdle. Thus the high school race is equivalent to beginning of a standard 400 meter hurdle race, but its placement on the track is shifted 100 meters around the track so it finishes at the common finish line on the straightaway, where the longer race would reach the same point near the end of the second turn.
For example, North America uses the reference rail as the line rail which is the east rail of tangent track running north and south, the north rail of tangent track running east and west, the outer rail (the rail that is further away from the center) on curves, or the outside rails in multiple track territory.

While races over imperial measured distances were very common in the first half of the 20th century, only the mile remains common today due to its historical prominence in track and field: all other imperial measured distance races became increasingly rare, and the IAAF deleted these events from the world record books in 1976.

Sometimes the same Tennant drawing reappears in another Dummies book with a new caption. Another constant in the Dummies series is "The Part of Tens", a section at the end of the books where lists of 10 items are included. They are usually resources for further study and sometimes also include amusing bits of information that do not fit readily ...
