Here we go... again.

What would the running world be without an event in the woods of Concord on the last Saturday of July? What could be better than an event with infinite possibilities? If you thought that the poundage of sweat, blood and God knows what other bodily fluids soaked into your glorious polyester running clothes worn at the Stevest was too much. To you we say, "Hold our Tecate!"
