Amputee runner Jacky Hunt-Broersma aiming to break world record with 102 marathons in 102 days

Jacky Hunt-Broersma runs like a woman possessed. And in a way, she is: The amputee athlete is trying to run at least 102 marathons in 102 days.

In 2001, while she and her Dutch husband were living in the Netherlands, Hunt-Broersma was diagnosed with Ewing sarcoma, a rare cancer more typically seen in children. Overnight, a golf
