For 31 years, Ann Trason's 18:06:24 course record at the Leadville 100 has stood as the time to beat – this weekend, it finally toppled as Anne Flower made her debut at the Colorado race and set a blazing new women's time.
The 35-year-old Colorado Springs resident surged ahead of Justin Grunewald with just two miles to go, arriving at the finish line on Saturday night in 17:58:19. That shaved eight minutes off Ann Trason's longstanding 1995 course record, and like Trason, placed Flower second overall behind David Roche. The closest any other female runner has come to Trason's time was in 2024, when Mary Denholm won in her debut 100 miler in 18:23:51.
