Finally, Williamson completed a thru-hike of the AT in 1995, by starting at the southern tip of Florida, hiking northward on the Florida Trail, continuing northward to get to the official start of the AT in Georgia at Springer Mountain, then completing the entire AT. After attempting to perform a round-trip, or "yo-yo" of the PCT in 1996, 1997, 2000, and 2003, Williamson became the first person to perform a round-trip of the PCT in 2004. That trip started at the Mexico–US border, went to the Canada–US border, then returned to Mexico, for a total of in 205 days. In 2006, Williamson became the first person to repeat the feat of "yo-yo"ing the PCT by becoming the second person to complete a PCT "yo-yo", doing it in 191 days. In 2007, Williamson married his longtime girlfriend Michelle Turley and the newlyweds celebrated their honeymoon by thru-hiking the PCT southbound from Canada to Mexico. In 2008, Williamson and Joe Kisner broke the unsupported speed record of the PCT, breaking Kisner's previous record-of 79 days, 21 hours and 42 minutes by over 8 days. The new record they set was 71 days, 2 hours and 41 minutes. This equates to an average distance of just under per day. In this case, "unsupported" means in the style of a thru-hiker, where supplies are obtained by hiking off the trail. In 2009. Williamson and Adam Bradley broke simultaneously two PCT speed records for both the unsupported effort and the supported speed record of ultramarathon runner David Horton. Horton’s previous record was 66 days, 7 hours, and 16 minutes, which Williamson and Bradley broke by about 21 hours. The new double record they set was 65 days, 9 hours, and 58 minutes. This equates to an average distance of approximately per day. Williamson and Bradley did their hike of the PCT without taking any detours or re-routes due to trail conditions. In addition, Williamson and Bradley did not accept any rides to re-supply in trail towns, which added approximately to their total walking distance. In 2011, Williamson set a new PCT speed record, unsupported, by completing the trek in 64 days, 11 hours, 19 minutes. Like the 2009 record, this new record broke both the supported and unsupported speed records. The new record equates to an average distance of approximately per day. Unlike the record set in 2009, this PCT speed record was set going from north to south. Williamson finished at the Mexican borderOctober 11. And finally as in 2009, Williamson did the hike of the PCT without taking any detours or re-routes due to trail conditions, nor accepted rides for re-supply. As of 2011, Williamson has had over a 19 year hiking career, logged over and thru-hiked the PCT 13 times.
Personal life
In 1996, while working at a convenience store in Richmond, California, Williamson was shot in the face during an attempted robbery. The bullet is still lodged in his head. Williamson states, “being shot, coming that close to death, that made me focus more on what I felt was important in my life,” and “if the hiking is very important to me, I’m going to pursue that, regardless of what other people may think. It made me more willing to just follow my passion.” Williamson also states, “I don’t own a home. I’m self-employed. I drive derelict vehicles I have to work on every weekend, but it’s been well worth it. The sacrifices I’ve had to make to get out on the trail every summer has been well worth it.” Williamson is married and lives in California with his wife.
