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.
[10] Thomas's first guide dog was Tennille,[11] who was born 27 November 2010 and accompanied him from 2012 until she retired in 2018.
