Trevor Thomas (hiker)
Trevor Thomas is the world's only professional long-distance blind hiker who as of 2016 had hiked over 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. He 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 Mt. Mitchell, Mt. Rose, Mt. Whitney, Mt. Elbert, and Mt. Friel. Thomas lost his sight at age 36. Guide dogs.
