ResFrac at the Comrades Marathon in South Africa (an Ultramarathon)

Comrades Marathon is the world’s largest and oldest ultramarathon.  The first race was in 1921. The number of registrants for this year was capped at 20k.  The marathon runs from the city of Durban to Pietermaritzburg (“up” run) or in the other direction (“down” run). The “down” run is a little bit longer at around 90 km, while the  “up” run is 87 km. This year we did the “down” run, but it was shortened to 87.7 km or  54.5 miles. “15 minutes less of pleasure” – as one of my friends said.
