In 2017, marathoner Simon Wheatcroft, who has retinitis pigmentosa, wired up with a new technology called corrective navigation for the New York City Marathon. His only human assistance would come from three other runners who would shadow him only for the purpose of helping him avoid collisions with other runners. He would do this using various devices, but most importantly with a previously untested device called a Wayband, which works by emitting vibrations rather than voice commands. Read Wheatcroft’s running story and what he encountered during the marathon in this article from the New York Times. Fast forward to 2021, and with some kinks worked out, the Wayband is ready to take off with an introductory discount offer. Find out all about it on the Wear Works site.
