Most of the athletes that participated in the 126th Boston Marathon on April 18, 2022, probably took some time to recuperate before embarking on another exhausting run. But not Jacky Hunt-Broersma. The Arizona-based ultra-runner completed another marathon the next day — and the day after. In fact, Jacky ran the grueling 26.2-mile distance for 104 consecutive days, from January 17 to April 30, 2022. Even more impressive, the 46-year-old did it with a prosthetic leg.
