A 10k race is 6.2 miles. One kilometer converts to .62 miles. Ten kilometers, therefore, converts to 6.2 miles. A 10k race is twice as long as the popular 5k race, which is 3.1 miles.
A 10k race is a long distance running competition. It is usually the second step for long distance runners after successfully completing a 5k run. To successfully run a 10k, a detailed plan must be in place. The plan should include scheduled runs each week, with increased distances over a specified amount of time. To prevent injury, a runner should wear the proper shoes, hydrate and stretch.
