Peter Riegel. Race time prediction formula, running course certification. 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 ...
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 ...
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 ...
Researchers in Japan try to figure out which miles matter most for long-distance runners
200 meters run at a slightly faster-than-mile race pace. 200 meters run at an easy pace to recover. Repeat 16 to 20 times. Performance payoff: The main benefit of this workout is speed. By doing ...
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.
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]
