Comrades Marathon in Durban/Pietermaritzburg
The Comrades Marathon is the world's largest and oldest ultramarathon, run between Durban and Pietermaritzburg in KwaZulu-Natal since 1921. Roughly 90 km long, the direction alternates yearly between the up run from Durban and the down run from Pietermaritzburg, held each May or June and drawing tens of thousands of entrants.
The Comrades Marathon was founded in 1921 by Vic Clapham, a World War I veteran who wanted to commemorate South African soldiers who had marched long distances during the East Africa campaign.
