Fastest known time

A fastest known time (FKT) is the speed record for a running or hiking route. Unlike most endurance sports competitions such as marathon world records, FKTs are self-organized and done alone or in small groups. FKTs are most popular on long trails suitable for thru-hiking or ultramarathon trail running such as the Appalachian Trail, the Pennine Way, and the John Muir Trail. rdf:langString
