BOSTON (AP) — An Arizona woman who lost a leg to a rare cancer is closing in on what would be a new world record — at least 102 marathons in 102 days. Jacky Hunt-Broersma began her unusual quest in mid-January, covering the classic 26.2-mile marathon distance every day. The South Africa native runs on a special carbon-fiber blade, completing most of her marathons on a loop near her home or indoors on a treadmill. She'll be running the Boston Marathon on April 18, which will be No. 92 in her streak. Hunt-Broersma says she hopes others realize they're stronger than they think.
