Louisiana man Jarrett Leblanc runs 62-minute half-marathon on a treadmill

On Sunday, a Louisiana man took to the treadmill at his local gym in Lafayette, La., attempting to break the Guinness World Record for a treadmill half-marathon. Jarrett Leblanc, a 2020 U.S. Olympic marathon trials qualifier, clocked a time of 62:50 over 21.1 kilometers, breaking the old mark of 63:08 from 2020 and raising money for a non-profit organization that provides camps and programs for children with heart defects.

Leblanc had the speed on the treadmill set at a ridiculous 12.5 mph for nearly the whole challenge. According to local news, Leblanc was six seconds ahead of the record through his first 5K split (14:54) and built a 13-second cushion, hitting 29:46 through 10K. He ended up breaking the previous mark by 18 seconds. The previous treadmill record was held by U.S. 2:12-marathoner John Raneri, who placed fourth at the California International Marathon in 2022.

The 32-year-old told local news that his inspiration behind targeting the record came from a friend who broke this same record while running on a treadmill at altitude. “He broke the record at an altitude, so with me doing it at sea level, I knew I already had an advantage,” he said. “The thought of having a World Record attempt would not only bring the community together but also the entire world to get behind a great cause to help the children.”

Leblanc works full-time as a registered diagnostic cardiac sonographer at the Lafayette General Medical Center, and wanted to use his platform and passion to raise money for Camp Bon Coeur, a camp for children with hearts that have needed mending. Leblanc has so far reached nearly $10,000 of his $25,000 goal.

This world-record feat isn’t Leblanc’s first running accomplishment. In 2015, he became the first Louisiana native to run a sub-four-minute mile on Louisiana soil, clocking 3:59.95 in front of his friends and family in Lafayette. His success has also led him to qualify for the 2016 and 2020 U.S. Olympic Marathon Trials.
