A slow-moving train in Pennsylvania might have brought some runners' dreams of the Boston Marathon to a halt.

Lehigh Valley Health Network's Via Marathon was in full swing on Sunday when a slow train crossed the race course near Allentown, stopping runners in their tracks.

Runner Charlie Young said the race was his last chance to qualify for the 2017 Boston Marathon.

The 22-year-old said he and more than 100 others were held up for about 10 minutes as the train crossed. He says he missed his qualifying time by eight minutes.
