PE Xpo was an idea which was founded by Paddy O'Reilly and Gerry McDonnell (both PE teachers at Trinity Comprehensive School, Ballymun) and Chris Steele (PE teacher) in January 2015. The main aim at that time was to promote PE as a subject in Ireland and to encourage students to research PE related topics.

PE Xpo is a competition that examines the science behind sport. It takes place in the Sports complex of Dublin City University.

Schools can exhibit all PE related projects.
