Diacore Gaborone Marathon

The Steinmetz Gaborone Marathon is a marathon in Gaborone, Botswana. The marathon is governed by the International Association of Athletics Federations and the Botswana Athletics Association. It is open for to ages 19 and up, and the race is a qualifier for the Comrades Marathon in Durban and Pietermaritzburg, South Africa, and the 2012 Olympic Marathon in London. The marathon is the second of its kind in Botswana, after the Bosele Marathon in Selebi-Phikwe.

The marathon was first established as the Gaborone City Marathon in 2009 and was first run on 18 April 2010. The 2011 race was cancelled due to financial issues. In 2012, Steinmetz Diamonds became the official sponsor of the marathon and renamed the marathon.
