At the halfway mark of the men's race in the 2013 Boston Marathon, Kenya's Dickson Chumba was the official leader, hitting the 13.1-mile point in 1:04:54 (4:57 pace, which is relatively slow for them). But really, Chumba was just part of a big lead group that includes defending champion Wesley Korir, Markos Geneti and heavy race favorite Lelisa Desisa.
American Jason Hartmann, who fought his way back into the lead group after falling back a bit, was technically a second behind the leaders in 10th place, but realistically the 2012 fourth-place finisher was right in the mix of it all.
Chumba, 26, mae his marathon debut in 2010 and finished second in both the Madrid and Italian races. He won the Rome City Marathon in 2011 and ran a 2:07:23 in the Frankfurt Marathon, but finished just seventh.
Fernando Cabada of the United States was 13 seconds back at the halfway mark.
