Quantum physicist, mom of three, and now, world record holder. Physics Professor Jenny Hoffman crossed the George Washington Bridge and headed for New York City Hall on Nov. 2 leading a throng of cheering supporters, having run more than 3,000 miles since leaving San Francisco City Hall on Sept. 16.

Hoffman, 45, traversed the U.S. in 47 days, 12 hours, and 35 minutes, beating the previous record of 54 days, 16 hours, and 23 minutes. The Clowes Professor of Science, who was on sabbatical, ran 15 hours a day on six hours of sleep each night through seven grueling weeks with the support of a dedicated crew.

A three-time national ultrarunning champion, Hoffman had made a record attempt in 2019 but suffered a devastating knee injury more than 2,500 miles in that forced her to stop. “Through surgery and rehab and pandemic and work and family life, I have dreamed every single day for four years about redoing and completing this run,” Hoffman said on her website, where she chronicled her journey.

Hoffman plans to submit documentation to Guinness World Records to certify her accomplishment. She’s already been credited the record by Fastest Known Time. Her next race will be the 24-Hour World Championship in December in Taipei, Taiwan.

As she rested her legs in her Cambridge office, the Gazette asked Hoffman to reflect on her record-setting run, and what’s next.
