The men's marathon was one of the road events at the 2019 World Athletics Championships in Doha, Qatar. Due to the heat in Doha, the race was scheduled to begin at 23:59 on 5 October 2019. Even with the unusual timing, high temperatures were expected to provide difficult conditions for running, but in the end temperatures dropped to around 29 °C (84 °F) and 50% humidity. The race was won by Lelisa Desisa of Ethiopia in 2 h 10 min 40 s, followed four seconds behind by his compatriot Mosinet Geremew. Amos Kipruto of Kenya was third in 2:10:51.
