Trevor Thomas (born 1968 or 1969)[1] is the world's only professional long-distance blind hiker and as of 2022[update] has hiked over 22,000 miles (35,000 km) solo.[2][3] He was the first blind person to complete the Appalachian Trail[4][5] on an unassisted solo hike, in 2008.[6][7] He hikes with a guide dog,[1] and uses sophisticated digital technology, emailing his route to his phone to convert to audible sections, using echo location to identify obstacles, and having a satellite beacon which updates his Facebook page with his location every 10 minutes: if he is in the wrong place or not making the expected progress his expedition coordinator is alerted.[6] He supports himself through speaking, writing, blogging and sponsorship, and has set up the Team FarSight Foundation to support young blind people in outdoor activities.[6][3]
Thomas's first guide dog was Tennille,[11] who was born 27 November 2010 and accompanied him from 2012 until she retired in 2018. Together they walked over 10,000 miles (16,000 km) and climbed five 14,000-foot (4,300 m) summits.[12] In 2016 she was said to be "currently the only dual mode dog capable of performing backcountry guide work in addition to her standard guiding duties".[11]
His new dog is Honolulu or Lulu. They met in October 2018. As of March 2019[update], Thomas was training Lulu for her new role.[13]
