Fully supported, ultrarunning-style multiday speed records on big trails probably began with David Horton's AT trip in 1991 (52d9h42m). Horton's time was broken by Pete Palmer in 1999, with 48d20h11m.
In 2005, Andrew Thompson beat Palmer's time, completing the AT in 47d13h31m. Here is an article about Thompson's trip. Thompson had tried but failed to break the AT record in 1998 and 2001.
