International Trail Running Association

International Trail Running Association (ITRA) is the governing body for trail running. It was formed in 2013, emerging from the 1st International Trail Running Conference held in 2012. Trail running was first recognised by the International Association of Athletics Federations (now World Athletics) in 2015 as a discipline of athletics. ITRA has, among other things, developed a points system for ranking the difficulty of specific trail routes and tracking the performance of runners across races.

ITRA is currently headed by Janet Ng, a co-founder of the Hong Kong Trail Running Association.
