Geoffrey Mutai won the Boston Marathon in 2011, running 2:03:02, the fastest time, under all conditions, on all courses, by a human being. But, due to sport rules, on a course not worthy for world records.
Be careful what you wish for, as the race took a bit out of Geoffrey. In the fall of 2011, Geoffrey won New York in 2:05:01, and in 2012, he won Berlin in 2:04:15, his PB.
London in 2013 was a DNF, but in the fall of 2013, Geoffrey came back and won New York in 2:08:24. His win in the NYC Half in March, and Mr. Mutai is now in London, ready to run a fine race across the streets of London.
