The Trail Las Rozas Run takes place on a Saturday morning in Las Rozas, Madrid, beginning at 09:30. Participants can choose from three distances: a 5K, a 10K, and a half marathon offered as a team relay. This allows for both individual participants and groups to compete in the longer distance.
The organizer characterizes the course as "competitive-family," suggesting a race designed for varied skill levels, not exclusively for elite trail runners. Tyr Producciones is the organizing body. The event provides timing services, medals, a sound system at the finish line, aid stations with refreshments, a runner's bag, a cloakroom, restrooms, medical support, parking nearby, and a prize raffle. It also functions as a solidarity event, incorporating a charitable cause.
