Non-championship accomplishments

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.^[8]

Obiri winning the 2024 Boston Marathon

In the 2023 Boston Marathon, Hellen Obiri won the race in a time of 2:21:38.^[9] 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.^[10]

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.^[11]
