Shannon-Leigh Litt, a 47-year-old criminal lawyer from Whangārei, New Zealand, completed her 1,000th ultramarathon on Saturday, setting a new women's record. Litt ran 51K each day, totaling over 51,000 kilometers. Guinness World Records verified each run with required evidence.

Litt began her streak on New Year’s Day 2024, initially aiming for 200 days. She surpassed previous records set by Megan Cassidy and Candice Burt. Litt managed her legal practice by running early and listening to work documents. Read more racing coverage.
