In September 2026, Colorado doctoral student Corey Murphey broke the women's world record for the North Channel swim. She completed the 21.4-mile route between Northern Ireland and Scotland in 9 hours, 11 minutes, and 34 seconds.

Why it matters

The record-breaking swim highlights Murphey's rapid ascent in endurance athletics following a series of major swims throughout 2026. Her performance demonstrates significant athletic achievement in cold-water conditions.

Murphey finished the 21.4-mile trek in 9 hours, 11 minutes, and 34 seconds, eclipsing the previous women's world record of 9 hours, 34 minutes, and 39 seconds. The swim took place in water temperatures in the mid-50 degrees Fahrenheit.
