Thomas Panek has completed 20 marathons, however, he made history on Sunday at the New York City Half Marathon. While visually impaired runners usually use human guides, Mr Panek became the first person to complete the race supported by guide dogs. A trio of Labradors - Westley, Waffle and Gus - each accompanied him for a third of the race. The team finished in two hours and 21 minutes. Mr Panek, who lost his sight in his early 20s, told CNN that while he appreciated the support of human volunteers, he missed the feeling of independence. It never made sense to me to walk out the door and leave my guide dog behind when I love to run and they love to run," he said. "It was just a matter of bucking conventional wisdom and saying why not. In 2015, Mr Panek established the Running Guides programme which trains dogs to support runners. "The bond is really important. You can't just pick up the harness and go for a run with these dogs," Mr Panek told CNN. "You're training with a team no matter what kind of athlete you are, and you want to spend time together in that training camp." Each dog wears a special harness and set of running boots, to protect their paws. Before the race, Mr Panek told Time magazine that guide dogs give visually impaired people the freedom to "do whatever it is a sighted person does, and sometimes, even run a little faster than them".
