I have a sprained ankle, a head full of bee stings and a cut on my neck from some stupid plant. The jungle marathon was the hardest race I have ever done. Unlike most races where there are easy days and hard days, this race just kept gnawing at you with steep hills, muddy swamps, the ever-present danger of snakes, stinging bees, ants and spiky plants. On other races, I could listen to music and run on auto-pilot. In the jungle, I needed total situational awareness of where I put my feet, my hands and where I was going. I was mentally tired every day. Just hopping over a log required a procedure because you never knew what thing could be on the other side and each day we had to climb under or over more than 50 logs
