Note: The Road Mile became an official world record event after September 1, 2023, on World Athletics Certified Courses only (i.e: elevation gradient must not exceed one meter per kilometer, start and finish line must not be more than half a mile apart). The winning times from the 2023 U.S. Road Mile Championships, on 25 April, were ratified by ...
Pace [6] in minutes per kilometre or mile vs. slope angle resulting from Naismith's rule [7] for basal speeds of 5 and 4 km / h. [n 1]The original Naismith's rule from 1892 says that one should allow one hour per three miles on the map and an additional hour per 2000 feet of ascent.
The road mile became an official world record event on 1 September 2023 which is why most performances prior to this date were not previously considered records. The winning times from the 2023 U.S. Road Mile Championships, on 25 April, were ratified by World Athletics as the inaugural road mile world records. [61] Correct as of September 2024.
Rollout or rollout allowance is an adjustment in timed acceleration runs used by North-American drag racing and enthusiast magazines [citation needed] to create approximate parity over time between historic 0 to 60 mph and 1/4 mile acceleration times and those measured today using the Global Positioning System (GPS).
Blue plaque recording the first sub-four-minute mile, run by Roger Bannister on 6 May 1954 at Oxford University's Iffley Road Track. A four-minute mile is the completion of a mile run (1.6 km) in four minutes or less. It translates to a speed of 15 miles per hour (24 km/h). [1] It is a standard of professional middle distance runners in several ...
One can also use the 1 in 60 rule to approximate distance from a VOR, by flying 90 degrees to a radial and timing how long it takes to fly 10 degrees (the limit of the course deviation indicator). The time in seconds divided by 10 is roughly equal to the time in minutes from the station, at the current ground speed.
The mile run and its metric 1500 metres equivalent have been held at the NCAA Division I Indoor Track and Field Championships since its founding in 1965. With the exception of two 1500 m races contested in 1984 and 1985, the mile is the only event on the NCAA schedule that has not transitioned from imperial measurements to metric.
In road events, the course is not required to be a circuit, but the overall decrease in elevation between the start and finish shall not exceed 1:1000, i.e. 1 m/km. In road events, the start and finish points of a course, measured along a theoretical straight line between them, shall not be further apart than 50% of the race distance.
