Non-championship accomplishments

Colorado's First Sub-Four Minute Mile

On August 3, 2020, Joe Klecker and Olli Hoare became the first people to ever break 4 minutes in the mile on Colorado soil. The long streak of no sub-4-minute miles is attributed to the elevation of the state.

Hellen Obiri Marathon Success

In the 2023 Boston Marathon, Obiri won the race in a time of 2:21:38. She then won the 2023 New York City Marathon in 2:27:23, becoming the first woman since 1989 to win both races in the same year.

At the 2024 Boston Marathon, Obiri won her second straight Boston marathon beating second place finisher, Sharon Lokedi, by eight seconds in a time of 2:22:37.
