An 80-year-old woman from New Jersey made history at the 2025 IRONMAN® World Championship in Kailua-Kona, Hawaii, becoming the oldest female to ever finish the grueling endurance race, officials said.

Natalie Grabow, of Mountain Lakes, completed the iconic triathlon in 16 hours, 45 minutes, and 26 seconds on Saturday, Oct. 11, marking a record-setting moment nearly 50 years after the event’s debut, according to IRONMAN officials.
