The term 'RACE DISTANCE' can refer to two common distances used in running races: the mile and the ten kilometer (or 10K). The mile is a unit of length equal to 1, 609 meters, or 5, 280 feet. It is commonly used in the United States and other countries that use the imperial system of measurement. The 10K is a distance of 10 kilometers, or 6.2 miles. It is a popular distance for road races and is often used as a benchmark for measuring running performance.
