On 9 June 2023, Norwegian runner Jakob Ingebrigtsen bested that time, running 7:54.10 to become only the second individual to run two miles in less than eight minutes. Ingebrigtsen also holds the record as the youngest runner to run a four-minute mile, having run 3:58.07 at the Prefontaine Classic in May 2017, when he was 16 years and 250 days ...
When the Olympic Games were revived in 1896, metric distances were run, including the 1500; however, most of the best milers in the world were absent, and the winning time of 4:33 1/5 by Australian Edwin Flack was 17 4/5 seconds slower than the amateur mile record, despite the fact one mile is 109.344 metres longer than 1500 metres.
Not all military bases have a running track, and tracking soldiers' laps and positions after 12 minutes is difficult. Testing is easier to administer when the distance is fixed and the finishing time measured. In his original book, Cooper also provided an alternate version of the test, based on the time to complete a 1.5 mile run. [1]
In a binary exponential backoff algorithm (i.e. one where b = 2), after c collisions, each retransmission is delayed by a random number of slot times between 0 and 2 c − 1. After the first collision, each sender will wait 0 or 1 slot times. After the second collision, the senders will wait anywhere from 0 to 3 slot times . After the third ...
The 4 × mile relay is an athletics track event in which teams comprise four runners who each complete one mile (1,609.344 metres) or slightly more than 4 laps on a standard 400 metre track. The event is not often run as most legacy 440 yard tracks have been converted to 400 metres, thus making 4 × 1500 or 4 × 1600 metres easier to manage.
In terms of judging a person's speed, the best method of timing is through lasers which start and stop the times when passed through. A laser start (from a stationary position) is more accurate for measuring pure speed as it does not register a runner's reaction time, however, this method of timing a 40-yard dash can affect the accuracy by as much as 0.5 seconds with the manual stopwatch method.
The standard middle distances are the 800 metres, 1500 metres and mile run, although the 3000 metres may also be classified as a middle-distance event. [1] The 1500 m came about as a result of running 3 + 3 ⁄ 4 laps of a 400 m outdoor track or 7 + 1 ⁄ 2 laps of a 200 m indoor track, [2] which were commonplace in continental Europe in the ...
In order to successfully run out the clock by kneeling, there must be less than 40 seconds on the clock if the opponent has two time-outs, 1 minute 20 seconds if the opponent has one time-out, or 2 minutes if the defense has no time-outs remaining, at the snap on a first down (an additional 40 seconds can be run off if the clock keeps running ...
