What Are Common Race Distances?

Common Race Distances

A lot of people are confused as to what distances all of these races and fun runs are. I’ve had people tell me, “Look at you, doing all these marathons!” It takes all of my energy not to correct them. I went into a GNC once and told the guy working there that I was training for a marathon and was looking for some supplements, and he asks, “How far is your marathon?” *FACEPALM*

So we thought we’d clear up all of the confusion and explain the most common race distances. Let’s start with how to calculate them:




  • 5k: (5 x .621) = 3.1 miles
  • 10k: (10 x .621) = 6.2 miles
  • 15k: (15 x .621) = 9.3 miles

Now, when it comes to the big dogs, you just need to know the length of a marathon. A marathon is always 26.2 miles unless otherwise specified (Ultra Marathon, etc.).

  • Half Marathon = 13.1 miles
  • Marathon = 26.2 miles

There, now doesn’t that all make sense? SOLVING PROBLEMS LEFT AND RIGHT.


Fun Marathon Fact:

A Marathon event was instituted in commemoration of the fabled run of the Greek soldier Pheidippides, a messenger from the Battle of Marathon to Athens. It is said that he ran the entire distance without stopping and burst into the assembly, exclaiming “νενικηκαμεν’ (nenikekamen)”, (“We wοn”), before collapsing and dying. (source: Wiki)
