The following release is published with permission from ATRA corporate member TrailRunAdvisor and features a new partnership with Gretel Planner.
Two of Europe’s fastest-growing trail running platforms are joining forces and setting their sights on the U.S. scene. Gretel Planner, a pioneering technology for personalized race planning, and Trailrunadvisor, one of the most trusted trail review platforms in Europe, have officially partnered to elevate the way runners prepare for races.
Already widely used in Spain, France, Portugal, and now expanding in Asia, Gretel Planner allows trail and ultra runners to create tailored pacing and nutrition strategies based on the course profile, terrain, elevation, and personal fitness. With over 35,000 strategies created and 700+ races onboarded, it has become a must-have for races that value both performance and safety.
TrailRunAdvisor, on the other hand, offers curated race reviews, athlete feedback, and terrain assessments — giving runners an insider view before they even pin a bib. The platform has just launched a brand-new version of its website, with improved navigation, more features, and enhanced tools to support the global trail running community. The combination of both platforms creates a powerful planning ecosystem for trail athletes.
Bringing these tools to the U.S. is the natural next step, says Jorge Vilanova, CEO of Gretel Planner. American trail runners are deeply connected to the challenge, the data, and the experience — and that’s exactly what we enhance.
Together, the platforms are now actively collaborating with races and communities across North America, offering free access for runners and technical value for race organizers, making events more professional, more international, and more athlete-centered.
