According to a press release, "Hall missed crucial training due to a quadriceps strain." Hall's 2:04.58 in 2011 was the fastest Boston Marathon run by an American.
Hall expressed his disappointment via Twitter:
Heart breaking to have to pull out of Boston. Want to thank all my sponsors and supporters for sticking by me through it all.— Ryan Hall (@ryanhall3) March 13, 2013
Hall has been hampered by injuries in the last year. He dropped out of the Olympic marathon in London because of a hamstring strain and did not compete in the New York City Marathon in November because of a quad strain. He did not run in the Boston Marathon last year because he was training for the Olympics.
Other previously announced elite male runners who have also cancelled because of injury include Moses Mosop, Shami Dawit, Eric Gillis, and Lucas Rotich. Two elite women also dropped out due to "lack of fitness" – Asefelech Mergia Medessa and Karolina Jarzynska.
Three runners were added to the elite field: Tirfi Tsegaye Beyene, Lelisa Desisa Benti, and Laban Korir.
