The Pro Trail Runners Association (PTRA) is a Switzerland-based non-profit organization formed by elite and professional trail runners. It represents athletes who meet its membership criteria, including qualifying rankings in major circuits or a paid contract to compete in trail running. The association aims to give runners a voice, defend their rights and interests, and work with sport stakeholders to shape a fair and responsible future for trail running.

PTRA focuses on clean competition, athlete rights, women’s equality, accessibility, inclusion, diversity, and environmental responsibility. It shares resources including accessibility, inclusion and diversity guidelines, a best practices guide, and environmental ethical boundaries. The association also promotes respect for athletes and event communities, stronger anti-doping measures, and practical steps to reduce the sport’s environmental footprint.

Eligible athletes can apply to join, and supporters can contribute through donations or an annual membership fee of 50 euros. Funds are used for the organization’s non-profit purposes and daily operations. Through advocacy, guidance, and collaboration, PTRA seeks to protect the values and sustainability of trail running.
