Lindsay Doherty had trained to race in a half marathon. But right after reaching the finish line of Scranton's 13.1 mile route, the runner collapsed and died. The 36-year-old was married and a mom of three young children. Her fellow competitors were heartbroken. "It was very shocking for me to hear," said one runner." It's unfortunately something that does happen in any kind of exercise, but on such a great day it was unexpected."
