The most common distances are 50 kilometres (31.07 mi), 50 miles (80.47 km), 100 kilometres (62.14 mi), 100 miles (160.93 km), and continue up to the longest certified race distance of 3100 miles. [1] Timed events range from 6, 12, and 24 hours to 3, 6, and 10 days (known as Multiday races). Timed events are generally run on a track or a short ...
Persian mile: Persia: 1,524: London mile: England: 1,609.3426 (statute) mile: England/UK: 1592: 1959: 1,760 yards: Over the course of time, the length of a yard changed several times and consequently so did the English (and, from 1824, Imperial) mile.

The term 'metric mile' (0.93 statute miles) was applied to this distance because it approximates one statute mile (1609.344 m). [ 1 ]
This length of long middle-distance or short long-distance race was 3,520 yards (3,218.688 m). Historically, the two-mile took the place that the 3000 m and the 3200 m have today. The first man to break the four-minute barrier for both miles was Daniel Komen at Hechtel, Belgium on 19 July 1997 in a time of 7
The backyard ultra or last one standing is a form of ultramarathon race where competitors must consecutively run the distance of 6.706 kilometres (4.167 mi) in less than one hour, which is a pace of 100 miles per 24 hours. The race is over when only one runner remains to complete a lap.
The yard (symbol: yd) [3] [4] is an English unit of length in both the British imperial and US customary systems of measurement equalling 3 feet or 36 inches.

Hundred mile runners complete a total of five loops, while the 100k is three and the 31k is one loop. The course is relatively flat and fast for a trail ultramarathon, with 7,900 feet (2,400 m) of cumulative vertical gain for the hundred-mile distance.
