How many miles is a 5K?

Let’s start with some basic facts. Just how many miles is a 5K? As explained in this article on half marathon training tips, the Ks in 5K and 10K stand for kilometers. One kilometer is about 0.62 miles. That means a 5K, or five-kilometer race, will be roughly 3.1 miles long. As you can probably guess, that makes a 10K about 6.2 miles long.

The Couch to 5K plan

In 1996, amateur runner Josh Clark created the Couch to 5K plan. He formed the training regimen with his mother in mind. When Clark began his personal running journey, he found the process difficult, painful, and often boring. He didn’t want that to be the case for his mom. Enter C25K.

Sources such as the National Health Service describe the regimen as “a running plan for absolute beginners.” The plan runs for nine weeks and changes as you gain experience. At the start, you’ll run three times a week, alternating between jogging and walking. A day of rest comes after each workout day.

As Clark explains, the C25K design focuses on elements like eliminating pain, welcoming newcomers, and delivering early victories. “If you feel like you’re kicking ass from the start, you’ll be eager to continue. Otherwise, you’ll decide that you suck, the program sucks, or both,” Clark writes.

If you want to keep things simple, check out the Couch to 5K app. It’s available on Android and iOS, helps track your runs, and features an easy-to-follow training plan. Not into apps?
