Today marks the one-year anniversary of the tragic death of Kenyan Sammy Wanjiru, at the age of 24, who was quite possibly on his way to becoming the greatest marathoner of all time. In his very short career Sammy was an Olympic Marathon gold medalist (2008), two-time winner of the Chicago Marathon (2009, 2010), winner of the London Marathon (2009) and twice the half marathon world record holder (59:16-2005, 58:33-2007).
His death really struck me last year especially because he was the winner of the 2009 Bank of America Chicago Marathon, which was my first completed marathon. During that race he ran the fastest marathon ever on U.S. soil (at the time).
