Not all military bases have a running track, and tracking soldiers' laps and positions after 12 minutes is difficult. Testing is easier to administer when the distance is fixed and the finishing time measured. In his original book, Cooper also provided an alternate version of the test, based on the time to complete a 1.5 mile run. [1]
The mile run (1,760 yards, [2] 5,280 feet, or exactly 1,609.344 metres) is a middle-distance foot race.. The history of the mile run event began in England, where it was used as a distance for gambling races.
The world record in the mile run is the fastest time set by a runner in the middle-distance track and field event. World Athletics is the official body which oversees the records. Hicham El Guerrouj is the current men's record holder with his time of 3:43.13, [ 1 ] while Faith Kipyegon has the women's record of 4:07.64. [ 2 ]
The most common middle-distance track events are the 800 metres, 1500 metres and mile run, although the 3000 metres may also be classified as a middle-distance event. [38] The 880 yard run , or half mile, was the forebear of the 800 m distance and it has its roots in competitions in the United Kingdom in the 1830s. [ 39 ]
Middle-distance running events are track races longer than sprints, ranging from 500 metres up to two miles (3218.688 metres). The standard middle distances are the 800 metres , 1500 metres and mile run , although the 3000 metres may also be classified as a middle-distance event. [ 1 ]
Peter Riegel (January 30, 1935 – May 28, 2018) was an American research engineer who developed a mathematical formula for predicting race times for runners and other athletes given a certain performance at another distance. The formula has been widely adopted on account of its simplicity and predictive accuracy.
That is, 7.92 units of distance are equivalent to 1 unit of climb. For convenience an 8 to 1 rule can be used. So, for example, if a route is 20 kilometres (12 mi) with 1600 metres of climb (as is the case on leg 1 of the Bob Graham Round , Keswick to Threlkeld), the equivalent flat distance of this route is 20+(1.6×8)=32.8 kilometres (20.4 mi).
[The mile-measuring carriage] is painted red, with pictures of flowers and birds on the four sides, and constructed in two storeys, handsomely adorned with carvings. At the completion of every li, the wooden figure of a man in the lower storey strikes a drum; at the completion of every ten li, the wooden figure in the upper storey strikes a bell.
