For a performance to be ratified as a world record by World Athletics, the marathon course on which the performance occurred must be 42.195 km (26.219 mi) long, [34] measured in a defined manner using the calibrated bicycle method [35] (the distance in kilometers being the official distance; the distance in miles is an approximation) and meet other criteria that rule out artificially fast ...
In running events up to 200 m in distance and in horizontal jump events, wind assistance is permitted only up to 2.0 m/s. In decathlon or heptathlon, average wind assistance of less than 2.0 m/s is required across all applicable disciplines; and maximum of 4.0 m/s in any one event. As an exception, according to rule 36.2, specific event ...
A pacemaker or pacesetter, sometimes informally called a rabbit, [1] is a runner who leads a middle- or long-distance running event for the first section to ensure a high speed and to avoid excessive tactical racing. Pacemakers are frequently employed by race organisers for world record attempts with specific instructions for lap times.
In the 400 meters, the strategy proven to be the most effective is starting off at a 70-75% pace and working up to 100%, or known as the threshold pace strategy. Examples of this race plan are Michael Johnson’s former World Record of 43.18 in 1999 and Cathy Freeman’s Olympic Gold Medal in 2000, [13] both 400 meters runners who benefited ...
Marathon. The marathon (from Greek Μαραθώνιος) is a long-distance foot race with a distance of 42.195 km (26 mi 385 yd), [ 1] usually run as a road race, but the distance can be covered on trail routes. The marathon can be completed by running or with a run/walk strategy.
The multi-stage fitness test (MSFT), also known as the beep test, bleep test, PACER test ( progressive aerobic cardiovascular endurance run ), or the 20m shuttle run test, is a running test used to estimate an athlete's aerobic capacity ( VO 2 max ). The test requires participants to run 20 meters back and forth across a marked track keeping ...
A pace is a unit of length consisting either of one normal walking step (approximately 0.75 metres or 30 inches), or of a double step, returning to the same foot (approximately 1.5 metres or 60 inches). The normal pace length decreases with age and some health conditions. [1] The word "pace" is also used for units inverse to speed, used mainly ...
Running is a method of terrestrial locomotion by which humans and other animals move rapidly on foot. Running is a gait with an aerial phase in which all feet are above the ground (though there are exceptions). [ 1] This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight, and the ...
