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.
An important class of predictive analysis methods has been developed for detecting concurrency errors (such as data races) in concurrent programs, where a runtime monitor is used to predict errors which did not happen in the observed run, but can happen in an alternative execution of the same program. The predictive capability comes from the ...
A coast-to-coast race has taken place several times since, including four races organized by Jessie Dale Riley and Michael Kenney from 1992 to 1995. Alan Firth organised two events in 2002 and 2004. In 2011 ultrarunner Serge Girard planned a new edition running from Los Angeles to New York starting June 19 and lasting for 70 days.
A distance medley relay is made up of a 1200-meter leg (three laps on a standard 400 meter track), a 400-meter leg (one lap), an 800-meter leg (two laps), and a 1600-meter leg (four laps) in that order. The total distance run is 4000 meters, or nearly 2.5 miles. Aside from the 400 meter segment, which is a sprint, all legs are a middle distance ...

Initially the correlation between the formula and actual winning percentage was simply an experimental observation. In 2003, Hein Hundal provided an inexact derivation of the formula and showed that the Pythagorean exponent was approximately 2/(σ √ π) where σ was the standard deviation of runs scored by all teams divided by the average number of runs scored.

Easy Goer and Sunday Silence both earned 124 speed figures in the 1989 Breeders' Cup Classic, which tied for the fastest speed figure earned in any Breeders' Cup race. [5] [6] [7] Easy Goer also ran a 122 in winning the 1989 Belmont Stakes, the best Beyer Speed Figure in any Triple Crown race since these ratings were first published in 1987. [8]
“My prediction has not changed,” Lichtman said on his YouTube channel. “I have frequently made my prediction correctly in defiance of the polls, it’s based on 160 years of precedent.”
