Fernando Armisén – Technical Trail, Ultra & Skyrunning Coach with Passion for Mountain Performance
Professional Trail & Skyrunning Coach | Specialist in High-Mountain Training, Ultra Endurance & Technical Performance
I’m Fernando Armisén — trail running coach, mountain athlete, and lifelong student of performance from Zaragoza, Spain.
My passion lies in helping runners of all levels prepare for the mountains — from fast vertical races and technical skyrunning to long-distance ultratrails with elevation and complexity.
At Arduua, I coach athletes across the world through our online platform, designing structured training programs focused on progressive development, race preparation, and technical efficiency.
My coaching philosophy balances science with mountain intuition — helping runners grow stronger, move better, and race with confidence.
My home base is the Tena Valley in the Spanish Pyrenees — a training laboratory of steep climbs, technical stone, high altitude, and endless sky.
It’s where I test methods, lead Arduua Camps, and continue to evolve as both athlete and coach.
