Jonathan started thinking he was ok at this running thing when he ran his first school cross country race at 8. He won, and beat all of the 9 year olds too!
Throughout school he ran cross country and began track running from 15 years old.
He would run cross country in the winter and then race track in the summer, competing at the 1996 Atlanta Olympics.
He then moved to the marathon and finished 21st at the Athens Olympic games in 2004 – following the historical course from the town of Marathon to Athens.
He tried his first mountain race in 1998, and won his first World trophy mountain title on the island of La Reunion in the Indian ocean. Jonathan has won the World Mountain Trophy 6 times, and held over 40 mountain race records.
