About Don Antonio Marcelo

What started as a personal journey eventually became a calling to help others experience the transformative power of trail and ultrarunning.

Coaching Philosophy

I coach with the belief that everyone is an athlete, regardless of pace, background, or experience. My coaching philosophy centers on building strong foundations through consistency, movement efficiency, and respect for the mountains. Trail and ultra training is not just about distance or speed but about learning how to manage effort, terrain, elevation, nutrition, and mindset over long hours.

I especially enjoy working with beginners and developing runners who are curious about the trails or stepping into longer distances for the first time. I focus on removing fear and overwhelm by breaking big goals into simple, manageable steps. Whether your goal is your first trail race, your first ultra, or simply becoming more confident and capable on technical terrain, I emphasize smart training, injury prevention, and long term progression.
