21 Over 90 years running 90 km

“Success supposes endeavour.”

— Jane Austen

Background The Comrades Marathon in South Africa between Durban and Pietermaritzburg has been run over 90 times since 1921.

Questions How many people take part? Who takes part and how has that changed over the years? How long do the best runners take and how long do most runners take? Are men much faster than women? Is there a difference in times between the “down” runs starting in Pietermaritzburg and the “up” runs starting in Durban?
