A marathoner came within feet of the finish line during Sunday’s Dallas Marathon and got assistance from a fellow runner to finish the race. Chandler Self, a 32-year-old psychiatrist from New York City, was leading the race but was running on empty. "When I watch that video, I think I cringe like everyone else," Self told Inside Edition. She could see the finish line when she collapsed. That was when Texas native Ariana Luterman, a high school senior, helped the fallen runner to her feet.
