Ann Trason

Trason won the Western States 100 a record 14 times between 1989 and 2003, often finishing high in the overall standings, and she was just as formidable on the road: two Comrades wins in the 1990s and a world 100km title. She also set track world bests and won Leadville, at altitude, in the same summers. Her range across trail, road and track, decades before the sport professionalised, is still the standard every versatile ultrarunner is measured against.
