ULTRA NAVARRO 50K invites runners to embark on an exhilarating journey through the lush forests of Spain, where each step challenges both body and mind. The race offers various distances tailored for different skill levels but all share a common thread: breathtaking natural scenery, rugged terrain, and demanding trails that test endurance, strategy, and resilience. The solo 50K route starts at dawn with a 5:00 AM departure, allowing participants to witness the early morning transformation of the forest as they push through varied landscapes. For those who prefer team dynamics, there are relay options for duos and larger groups, each covering significant distances while fostering camaraderie. Throughout the course, hydration stations appear roughly every 2.5 kilometers, ensuring runners stay hydrated in the challenging conditions. Every 10 kilometers, aid points provide essential nutrition with isotonic drinks, bananas, Coca-Cola, and salty snacks to replenish energy effectively. Medical support is strategically placed approximately every 15 kilometers, offering advanced care for any unforeseen issues that may arise during this demanding race. Upon completing their journey through the forest, runners can enjoy a recovery area equipped with free massages, ice baths, and massage devices at G2P Space. The event also features a vibrant food truck plaza where participants can refuel with delicious meals after conquering the challenging terrain of ULTRA NAVARRO 50K.
