It's well known that the current mile world record of El Guerrouj is the longest-lasting mile WR in modern history, and many track fans know that the shortest-lasting mile WR is Steve Ovett's 3:48.40 from Aug. 26, 1981, which lasted only two days before Sebastian Coe broke it.
Ovett's WR was run in Koblenz, West Germany, and the meet was originally scheduled to hold a 1500m but not a mile race. Since Ovett's earlier mile WR had been eclipsed by Coe the week before, Ovett requested that a mile race be held, and the meet directors decided to have both a 1500 and a mile at the meet. The funny thing was, the track at Koblenz didn't even have a starting line for the mile painted on the track. The officials had to measure 9.344 meters from the finish line and draw the starting line on the track surface with chalk!
If you pause the video JUST RIGHT at about 0:02 in the linked video below, you can see the chalked start line, which doesn't look very professionally done at all. I'm kind of surprised the authorities ratified the record, but since the WR was beaten two days later, they may not have cared as much about precision in this case.
