The Nairobi Marathon is an annual road running competition over the marathon distance usually held in October in Nairobi, Kenya.^[1] First held in 2003, the competition expanded and now includes a half marathon race along with the main race.^[2]

The marathon course starts on Uhuru Highway outside Nyayo National Stadium and heads roughly northward, wandering through the city center, before heading east on Wangari Maathai Road.^[5] The course then hits a turnaround point, and heads back to the stadium before heading southeast on Mombasa Road.^[5] The segment on Mombasa Road is a loop that is repeated twice before the course ends with a finish inside the stadium.^[5]
