10K Race

One kilometer converts to .62 miles. Therefore, a 10K race is the equivalent of 6.2 miles. The kilometer is the primary measurement unit for expressing large distances throughout most of the world, though the United States still uses the mile as its standard. The popularity of 10K races lies in the fact that, for most adults, the 10K distance is long enough to represent a challenge but short enough to remain accessible for an untrained runner. For a real world comparison, you would have to run a football field (including the end zone) 91.14 times to complete a 10K.
