. >> british motorcycle racer peter hickman is one of the best in the world. and a 13-time winner of a race known as the isle of man tt. short for both tourist trophy and time trial. not long before we met hickman, we watched him fly over the first jump on the course at a place known as ago's leap. >> you go by ago's leap today, and truly it was a blur. it was just like -- a speeding bullet. how fast do you think you were going when you went by there? >> around 185 to 195 mile an hour, somewhere around there. it's top gear. >> reporter: besides the blinding speeds, what truly makes the isle of man tt unique is that it is run on public roads that are open to normal traffic until just 30 minutes before racing begins on a 37-mile course that covers much of the island. running through villages and pastures, with riders taking more than 200 turns just inches from rock walls and buildings and residents. >> you initially race through a village and it just feels like you shouldn't be doing it, but we're allowed. >> on the isle of man. >> on the isle of man. >> reporte
