Philmont began using pre-planned treks in 1969 using a document titled "Itineraries". In 1972 the title of this document was changed to "Philmont Expedition Planning" or "PEP". In 1974 the title was changed again to "Philmont Expedition Adventure Key to Superactivities" or "PEAKS". The number of pre-planned itineraries slowly grew from the low 20s to 30. In 2000 the title was changed to "TREKS" and has offered 35 pre-planned itineraries. 7-day treks were first introduced in 2014. 9-day treks were introduced in 2020.
