On today’s show: Uganda’s Jacob Kiplimo just rewrote the history books, obliterating the world half marathon record by an eye-popping 48 seconds in Barcelona. Meanwhile, Grant Fisher decided one world record wasn’t enough, so he went ahead and took down two in a week—because why not? Also: Jakob Ingebrigtsen is breaking world records, dropping Instagram captions, and casually reminding everyone that he’s still that guy.

Along the way, he also shattered his own 1500m world record, becoming the first man to break 3:30 indoors (3:29.63).

Grant Fisher’s Historic Week: Two World Records in Seven Days — Grant Fisher has rewritten the history books, breaking two world records in just one week—the 3,000m at Millrose (7:22.91) and the 5,000m in Boston (12:44.09). This is the most dominant stretch of American distance running ever witnessed indoors.
