An endurance cyclist from New York has climbed over 4 million feet (1.2million meters) on his bike in the past calendar year, the equivalent height of 138 Mount Everests. 

Keith Roy does the majority of his riding on the indoor training app Zwift, pedalling for up to 10 hours a day as he works from home.
