Pace [6] in minutes per kilometre or mile vs. slope angle resulting from Naismith's rule [7] for basal speeds of 5 and 4 km / h. [n 1]The original Naismith's rule from 1892 says that one should allow one hour per three miles on the map and an additional hour per 2000 feet of ascent.
The metre per second is the unit of both speed (a scalar quantity) and velocity (a vector quantity, which has direction and magnitude) in the International System of Units (SI), equal to the speed of a body covering a distance of one metre in a time of one second.
To help compare different orders of magnitude, the following list describes various speed levels between approximately 2.2 × 10 −18 m/s and 3.0 × 10 8 m/s (the speed of light). Values in bold are exact.
Roddie Haley ran 59.82 i in Oklahoma City on 15 March 1986, but this time was rejected as a record due to an incorrectly measured track. Haley also ran a 59.90 i in Oklahoma City on 14 March 1987, but this time was rejected as a record for the same reason.
The time it takes a vehicle to accelerate from 0 to 60 miles per hour (97 km/h or 27 m/s), often said as just "zero to sixty" or "nought to sixty", is a commonly used performance measure for automotive acceleration in the United States and the United Kingdom. In the rest of the world, 0 to 100 km/h (0 to 62.1 mph) is used.
Thus, speed is necessary, and it seems that the more aerobic conditioning, the better. Faith Kipyegon from Kenya holds the women's world record: 3:49.04 set in Paris on 7 July 2024. [11] This is a difficult distance at which to compete mentally, in addition to being one of the more tactical middle-distance track events.

The cooper test which was designed by Kenneth H. Cooper in 1968 for US military use is a physical fitness test. [1] [2] [3] In its original form, the point of the test is to run as far as possible within 12 minutes.
