Of the 27,487 runners in the 2016 Boston Marathon, 39 were visually impaired. Simon Wheatcroft shares his personal story as a blind runner and his experiences using Google Glass as a tool to help him run independently. Simon is working with IBM to develop a running app to enable blind runners to run safely and independently. Simon piloted a version of the app at the Boston Marathon and plans to use the app again in a seven-day desert run in the Namibia at the end of this month. He is also interested in Google's Project Tango, technology that will give mobile devices spatial vision.
