A blind ultramarathon runner is attempting to run the New York Marathon without a guide but will use a navigation device that uses vibrations.
Simon Wheatcroft, 35, from Doncaster, England lost his sight from a degenerative eye disease at age 17. He has spent the last seven years experimenting with technology to enable him and other visually impaired people to navigate independently.
The Wayband device guides people to a destination using vibration rather than audio alerts, and will enable him to avoid the other runners in his path in NYC on November 5.
"Technology has enabled me to strive for the impossible. I want to continue using it to push the boundaries of what I am capable of achieving - and to ensure technologies exist that can assist everybody, whether they're running a marathon or simply walking through their home town," said Wheatcroft.
