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.

Last month, a little more than two-thirds toward her goal of setting a new world record for back-to-back marathons, the South Africa native posted something on Twitter that got people talking.

“The first thing I did after my run today was take off my leg. Felt so good,” she tweeted. “Marathon 69 done. 31 marathons to go.”

That was last month, and she’s still running — covering the classic 26.2-mile (42.2-kilometer) marathon distance day in, day out, rain or shine, occasionally on a treadmill but mostly on roads and trails near her home in Gilbert, Arizona. If her streak remains intact heading into the Boston Marathon on April 18, it’ll be marathon No. 92.

Unlike the 30,000 others running the storied course, Hunt-Broersma, 46, will have done a marathon the day before. Somehow, she’ll have to rally body and soul to run another the day after. And another after that. And then eight more.
