ABOUT FUego y agua Trail Runs

Started in 2008, Ultra Fuego y Agua is a series of distance-based trail runs on Isla de Ometepe. The courses use the island’s natural terrain: dirt trail, beach, paved road, technical single-track, dense forest, mud, and the ascents and descents of Volcán Concepción and Volcán Maderas.

Expect heat, elevation, and changing surfaces. The terrain is demanding. Preparation matters.

Distances include the iconic 50K & 100K Ultras, that go up and over the volcanos, 14K & 28K Trail Races, and a Kids Race. Also this year we are introducing the Vertical K race up Volcan Concepcion!

All races start and finish at Hotel Villa Paraíso on Playa Santo Domingo, Isla de Ometepe, Nicaragua.

“If you want to speak with God, run an ultra. If before speaking with God you want to be with the Devil...run FUEGO Y AGUA”
