At age 18 Charles became interested in coaching, gained through teaching children whilst studying for his degree in physical education. In 1987 he committed full-time to coaching and was selected to be the coach for the Dutch javelin team. After a couple of years building his experience as a coach, he was promoted to the role of technical director of combined events.
