The cyclo-cross rider and mountain bike rider, from Wingerworth, competed for the GB junior squad at the World Championships, finished second in the National Championships and is part of the Olympic Development Programme.
William says: "I currently train five to six days a week, and often twice a day, my training sessions lasting between 40 minutes and three hours.
"Being a mountain biker requires skills from all aspects of cycling and therefor my training sessions vary a lot from day to day.
"Last year I had the fortune to be selected for two World Championships in mountain biking and cyclocross. It was an incredible experience, and it really inspired my motivation for this season.
"Throughout winter my training will be focused toward the 2016 mountain bike season in the summer, however I hope to still have a competitive cyclocross season.
"My target for this year is to compete in the Cross Country National Series and Championships and hopefully achieve podiums in both, and, if selected, improve on my results in the World Championships.
"My ultimate aspiration is to compete in an Olympic games for my country, and hope to do this by moving up through the British Cycling programme, alongside a lot of hard work."
