A 5K run is 5 kilometers long, which is about 3.1 miles.

For a bit more context:

  • 5 kilometers = 5,000 meters.
  • On a standard 400 m track, that’s 12.5 laps.
  • Many walkers finish a 5K in about 45–60 minutes, while many beginners running it will be around 30–40 minutes.

So in simple terms: a 5K is 3.1 miles, and for most people it takes somewhere between half an hour and an hour to complete, depending on whether you run or walk.
