The fellow in the next photo is Ali Ahmed. I was just a short distance behind him when I saw him crash. He was unconscious for a few seconds and had a slight concussion. I ran back a ways to summon these two KWS (Kenya Wildlife Service) guys. They radioed for help and he was eventually taken by helicopter to a nearby hospital. I found out later that he was okay, although quite banged up and minus one tooth.
Later on, I had a puncture on my tire. When I attempted to fix it, my pump broke! This gal stopped and tried to help me. But, to make a long story short, I ended up walking my bike the last 3 kilometers of the race. I didn't mind, though. I'd had an absolute blast!
