Brian Robinson is a competitive distance hiker and long-distance runner, holding multiple world-firsts and ultramarathon world records.

[2] In 2000, Robinson decided to take a six-month leave of absence from his job at Compaq and attempt the Pacific Crest Trail with his father Roy, who himself is a seasoned backpacker.

Support for his pursuit ranged from notes of encouragement in trail registers, to regular food resupplies mailed to strategic points along the route,[3] and even a complete equipment replacement by a near-stranger after his backpack, containing most of his original gear, was lost.

During Robinson's travail, he overcame several emotional obstacles including having his pack misrouted during a bus transfer, discovering on September 12, 2001 that the US had been attacked, and encountering a woman that might have been "the one.

In 2008 he set the record at the Barkley Marathons, a grueling 100+ mile course in Frozen Head State Park, Tennessee.
