Jacky Hunt-Broersma

Jacky Hunt-Broersma is an American amputee ultramarathon runner who was born and raised in South Africa. Hunt-Broersma lost her leg to Ewing sarcoma in 2001 when she was 26 years old. She started running in 2016. She quickly progressed from running 5 km races to running ultramarathons.

In 2019 Hunt-Broersma became the first amputee to compete in the TransRockies Mountain Stage Race in Colorado.

In 2020 she became the first amputee to run 100-miles on a treadmill, running it in 23hr 38m. While she originally planned to do it with an in-person race at the Umstead 100, she did so virtually due to the COVID-19 cancellations.

Hunt-Broersma hoped to run one hundred marathons in one hundred days, which would have been the world record for consecutive marathons by a woman,  but British runner Kate Jayden completed her 101st marathon during Hunt-Broersma's quest, so Hunt-Broersma increased her goal to one hundred and two consecutive marathons. Hunt-Broersma ended up running 104 marathons in 104 days, finishing this in April 2022. These 104 marathons included the inaugural para athletics division of the 2022 Boston Marathon.
