Rotterdam Marathon
The Rotterdam Marathon often produces very fast times, as the course is flat and weather conditions are typically favorable. Between April 1985 and September 1998 the world best time had been set at Rotterdam, by Carlos Lopes and Belayneh Dinsamo respectively. As of April 2012 six different runners ran a sub 2:05:00 time and four of the ten fastest marathon runners ever ran their fastest time in the Rotterdam Marathon.
