Nicaragua’s legendary volcanic trail race will make its World Championship debut on Isla de Ometepe in March 2026.

/ENDURANCE SPORTSWIRE/ – The One Hundred® Group is proud to announce that Ultra Fuego y Agua, Nicaragua’s most iconic trail race, will officially join the One Hundred® Endurance Trail World Championship series.

Held annually on Isla de Ometepe, a breathtaking island in Lake Nicaragua formed by the twin volcanoes Volcán Concepción and Volcán Maderas, Ultra Fuego y Agua is one of Central America’s longest-running and most challenging trail events. Since its establishment in 2008, the race has attracted both international and local athletes drawn by its dramatic volcanic landscapes, raw natural beauty, and uncompromising terrain. The 2026 edition will take place from 6-8 March 2026.

Renowned for its extreme endurance demands, Ultra Fuego y Agua perfectly complements the One Hundred® Endurance Trail World Championship. Courses feature steep volcanic ascents and descents, dense forest, sandy beaches, technical single-track, dirt roads, and deep mud, creating a uniquely demanding race environment that tests physical strength, mental resilience, and adaptability.

The event’s flagship challenge is the 100K Ultra, featuring approximately 6,000 metres of elevation gain, starting at 3:00am on Saturday, 7 March 2026. The race programme also includes the Vertical K challenge running up Volcán Concepción, 14K and 28K trail races, a 50K Ultra with two ascents of Volcán Maderas, and a Kids Race, making it a true festival of trail running for all levels.

Ultra Fuego y Agua embodies the spirit of adventure and community that defines world-class endurance trail racing. The event is owned and directed by Thomas Blanc, an experienced event organiser and accomplished ultra trail runner and obstacle racer, whose firsthand understanding of endurance sport shapes every aspect of the race. Leading a seasoned team of staff and volunteers, Thomas ensures meticulous planning, athlete safety, and on-course support, with rugged courses that are GPS-mapped, marked with reflectors, and marshalled at key points, preserving the event’s raw and authentic character.

Thomas Blanc, CEO of Ultra Fuego y Agua:

“It is a true honour for Ultra Fuego y Agua to join the One Hundred® World Championship Series. This race was born on a raw volcanic island, built by a community of passionate runners, and shaped by years of pushing limits in one of the most demanding environments on Earth. We are proud to showcase Isla de Ometepe and its volcanoes to the world, and excited to welcome athletes who are ready to experience trail running in its purest, most authentic form.”
