Haile Gebrselassie broke the marathon world record in Berlin on Sunday, with an official time of two hours, four minutes and 26 seconds. At the half way mark he was at 1:02:29. He had his fastest kilometer split of 2:50 at 35 k. It all comes down to speed. The winner will always be the person who can sustain the highest percentage of their maximum speed. Look at this guys track times, anyone who thinks distance running is about pounding long slow miles needs to rethink their approach. I have always loved to watch this guy run because I felt he was the model of running efficiency, a very compact stride that enabled him to instantly change gears.
