November 9, 2025
The Tunnel Hill 100 in Vienna, Ill., has earned a reputation for producing world-record performances, and 2025 may go down as its most historic year yet. On Sunday, Ireland’s Caitriona Jennings and Anne Flower of the U.S. set new women’s world records (to be ratified) at the 100- and 50-mile distances, each running with remarkable control and consistency.
