Trevor Thomas (hiker)
American blind hiker

Trevor Thomas (born 1968 or 1969) is an American blind hiker. As of 2022 he has hiked over 22,000 miles (35,000 km) solo. He was the first blind person to complete the Appalachian Trail on an unassisted solo hike, in 2008. He hikes with a guide dog, 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. 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.
Thomas has hiked the Pacific Crest Trail, the Tahoe Rim Trail, the John Muir Trail, Long Trail, the Colorado Trail, and the North Carolina's Mountain to Sea Trail. He has climbed to the summits of Mount Mitchell, Mount Rose, Mount Whitney, Mount Elbert, and Mount Friel.
Thomas lost his sight at age 36.
Guide dogs
Thomas's first guide dog was Tennille, 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.

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 19, 2026.

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
