Jason Hartmann looks like an unlikely marathoner. In Monday’s wilting mid-80s temperatures, the 6-foot-3-inch, 31-year-old Michigan native came striding down Boylston Street, his pace strong, his head held high, still boasting enough energy to wave to the crowds. He ran across the line to claim fourth place in the Boston Marathon in 2 hours, 14 minutes, 31 seconds, the first American to finish.
Hartmann grew up in Rockford, Mich., and went to college at the running mecca of Oregon. He now lives and trains in Boulder, Colo., and his running credentials include qualifying for two Olympic marathon trials, a spot on the US team at the Pan American Games, the World Cross-Country Championships, and the World Half Marathon Championships.
