A half marathon is a road running event of 21.0975 kilometres —half the distance of a marathon. It is common for a half marathon event to be held concurrently with a marathon or a 5K race, using almost the same course with a late start, an early finish or shortcuts. If finisher medals are awarded, the medal or ribbon may differ from those for the full marathon. The half marathon is also known as a 21K, 21.1K, or 13.1 miles, although these values are rounded and not formally correct.

World Athletics Label Road Races are races that World Athletics designates as the "leading road races around the world." The classification was first introduced for the 2008 running season, upon the suggestion of the IAAF Road Running Commission. The races are split into three categories: marathons, half marathons and other. Within the "other" category are traditional road race distances, over which World Athletics world records can be set, along with some "Classical races", which span unusual distances. The Labels are considered a prestigious award by race organisers, and include the six World Marathon Majors.
