Harry Jeffery is a 14-year-old British obstacle racer, four-time world champion and Guinness World Record holder.
Harry’s journey began at six years old with a simple challenge: make it across the monkey bars. Obstacle racing became the place where his confidence, determination and ability came alive.
Eight years later, he has won world titles in the Bahamas, Costa Rica, Sweden and China—while balancing school, training and life as an ordinary teenager from Colchester.
