Previous Management

Peter Bakwin


With a PhD in Physics from Harvard University, Peter is extraordinarily qualified to keep track of your FKT efforts, fairly and accurately. Peter diligently maintained the FKT website ( for 10 years. He is also the only person to have completed the Hardrock Double (100 miles in one direction then 100 in the other, all within the normal cutoffs), along with countless other routes in the mountains and deserts of the west.

Buzz Burrell


Along with Peter, Buzz has helped popularize the term "Fastest Known Time", starting when they set the FKT on the John Muir Trail in the year 2000, a year after his FKT on the Colorado Trail. He formerly managed Ultimate Direction, a manufacturer of adventure and running packs, and previously managed the La Sportiva Mountain Running Team. Buzz's proudest accomplishment is not having died yet.

Jeff Schuler


Jeff develops websites and web applications through his company Substrate Websoft for organizations that focus on environment, empowerment, and education. Current client projects include the Cleveland Museum of Art and the Cleveland Metroparks' map app. He alternates between training for road marathons with the Boulder Track Club and enjoying the trails and rocks around Boulder. Besides work and running, Jeff plays Brazilian music on the violin and mandolin. (@digmob)
