How long is a 5k in miles?

A 5K run is 5 kilometers, and there are 0.62 miles in a kilometer; a 5K run is 3.1 miles long. When running in an actual event, the distance will likely be marked in kilometers instead of miles.

Typically, a 5k should never be attempted without a training program. There are a number of different running regimens all geared towards helping runners go from running less than a mile, to a mile and on up, until they are able to eventually run the entire 5K route. As of 2014, the largest 5k is the Race for a Cure: DC, which supports the Susan G. Komen foundation.
