World records in the marathon are ratified by World Athletics, the international governing body for the sport of athletics.
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.

The 10-mile run is a long-distance running event over a distance of ten miles (16.1 kilometres). It can be held on a road course or on a running track. Also referred to as a 10-miler or 10 miles run, it is a relatively common distance in countries that use the mile as a unit of measure. Ten miles is roughly an intermediate distance between the 10K run and the half marathon (21.1 km). The level of endurance required to run the distance means it attracts more seasoned runners than shorter events and usually requires a period of preparation for first-time attempts.
The women's marathon was one of the road events at the 2019 World Athletics Championships in Doha, Qatar.

Even with the unusual timing, the temperature was above 30 °C (86 °F) and the humidity over 70 per cent, making conditions difficult for running. Only 40 of the 68 entrants finished the race, which was won by Ruth Chepng'etich of Kenya in 2:32.43; the slowest winning time at the World Championships. Bahrain's Rose Chelimo was second in 2:33.46, with Helalia Johannes of Namibia third in 2:34.15.
