13.1 miles is the distance of a half marathon, sometimes referred to as a mini-marathon or halfathon.

For the recreational runner, it will take you between 1 hour 50 minutes to 2 hours 40 minutes to finish one. Some people finish them faster (I envy you) while others take longer.

Below are some guides for preparing for this distance. If you are new to running, try preparing for a 5K (3.1 miles) first, before attempting to tackle this distance.

Good luck.
