Brynn Hauxwell on his trek of Hadrian's Wall. See SWNS story SWLEwall. A disabled teen has become the first person to complete an 84 mile trek of Hadrian's Wall - in a WHEELCHAIR. Inspirational Brynn Hauxwell, 17, who has autism, ADHD, severe asthma and fixed ankle contractures, took on the historic trail on the border between England and Scotland as part of a charity challenge. Brynn, from Shetland, had dreamt of completing the route after he visited some of the museums and saw some parts of the wall in his wheelchair when he was 12. The arduous journey - which began in Bowness-on-Solway, Cumbria on May 27 and ended 10 days later at Wallsend, near Newcastle - saw Brynn and his team travelling around eight to nine miles a day and at times going as slow as one mile an hour.
