He ran at a much more conservative pace than the lead pack did, and gradually moved from 21st place at the 15k mark up to 10th at the 40 km mark. His teammates Dathan Ritzenhein and Brian Sell finished 9th and 22nd, respectively. Hall was chosen as the 2008 Road Runner of the Year in the Open Male division by the Road Runners Club of America. On April 20, 2009, Hall participated in the 2009 Boston Marathon, finishing third overall in 2:09:40 behind Deriba Merga of Ethiopia and Daniel Rono of Kenya. Merga and Rono finished with times of 2:08:42 and 2:09:32, respectively. He returned to the race in 2010, but only managed fourth place, although his time of 2:08:41 was the fastest ever by an American at Boston. In 2010, Hall finished fourth in the Boston Marathon, and fourteenth in the Philadelphia Distance Run half marathon. Due to fatigue, he withdrew from the Chicago Marathon.
