1600 meters is a middle distance track and field running event that is slightly shorter than the more common mile run, and 100 meters longer than the much more frequent 1500m run. It is a standardized event in track meets conducted by the NFHS in American high school competition, often being colloquially referred to as "the mile".
Many track and field statisticians use a conversion factor estimate of 0.24 seconds added to any hand-timed mark in the 100 m or 200 m event, and 0.14 seconds to any hand-timed mark in the 400 m or longer event: these conversion factors are only applicable for comparing marks from a variety of sources, and are not acceptable for record purposes.
The proper length of the first lane of a competitive running track is 400 m (1,312.3 ft). Some tracks are not built to this specification, instead being a legacy to imperial distances such as 440 yd (402.336 m), equivalent to a quarter of a mile.
2. 200s. This simple interval workout will get you to five to six miles on the track. Trade off between running 200 meters slightly faster than your mile pace and 200 meters of easy recovery.
Unlike most track relays, each member of the team runs a different distance. 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.
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.
Track gauge conversion is the changing of one railway track gauge (the distance between the running rails) to another. In general, requirements depend on whether the conversion is from a wider gauge to a narrower gauge or vice versa, on how the rail vehicles can be modified to accommodate a track gauge conversion, and on whether the gauge conversion is manual or automated.
