Buzz Burrell

Buzz Burrell, born on 31 October 1951, is an American ultrarunner, outdoor athlete and businessman who began trail running and ultramarathons in the late 1960s and early 1970s at events such as the Pikes Peak Marathon. He gained notoriety for ultra-endurance events and backcountry travel, which led him and Peter Bakwin to invent the Fastest Known Time concept and its website, and he set fastest times on routes such as the Colorado Trail and the John Muir Trail. He is a USATF Masters Trail Champion, has managed the La Sportiva mountain running team, and was inducted into the inaugural TrailCon Hall of Fame in June 2025.
