Every marathon is a challenge itself but I don’t remember suffering more than in Singapore, mainly psychologically. It was a never ending fight with the time and intestines. If you want to know more, read here. The below report doesn’t give much running data (more walking data), until the 10 kilometer I was somehow running, from the 10 KM it was a fight. Paradox is that this one I will remember much much longer than those I did under 3 hours and 30 minutes.
