If you saw the fire and medic units responding to Lincoln Park this afternoon – Ari did, and e-mailed us to ask what happened – here’s what we have found out: During the high-school cross-country meet under way at the park this afternoon, three runners were “treated for overexertion,” according to Seattle Fire spokesperson Kyle Moore. He says all three are girls; one, 14, was taken to Children’s Hospital “as a precaution,” according to Moore, while the other two “were examined but did not need transport.” That’s all the information available so far.
