I was covering the Comrades Marathon this weekend, which entailed flying to Durban, I missed my flight, by about two minutes, so had to wait two hours for the next one, but I got there eventually.
On race day, I had to wake up at about 02h30 to get to the start of the race, jumped on the back of a motorcycle and slowly made our way along to the finish, stopping to photograph various points of the course, after hopping on and off the bike for 0ver 6 hours, I'll admit I have stiff legs, I can only imagine how sore the legs are of the guys that actually ran the race are.
The next day you can see all the "Comrades shuffles" all over Durban.
