His MSc Thesis was based on Elite Training Systems used within High Performance Sports, namely athletics. More specifically, he looked at the decision making process of an Elite Coach (Dan Pfaff), searching for the “why” behind his program design.

This led to Jonas’ involvement in Athletics and he became an Apprentice Coach for UK Athletics in 2009 under the tutelage of Dan Pfaff. He was also selected to be part of the Elite Coach Apprentice Program run by UK Sport.

Jonas is now a world renowned sprints coach and known for his technical expertise in sprinting.
