The Reverse Aging Challenge LogoThe Reverse Aging Challenge

A place where your system can finally settle

Guaro is the most grounded way to enter The Reverse Aging Challenge. A quiet hillside basecamp designed to reduce friction, restore rhythm, and make healthy change sustainable.

March 21 - March 27, 2026Only 4 spots left

A small-cohort, science-informed healthspan program led by Oscar Trelles.

Highlights

  • Daily guided practices in breath, food timing, movement, and cold/heat, introduced gently and reinforced through repetition
  • A small, supportive cohort with direct access to coaches throughout the stay
  • A setting designed to remove distraction, urgency, and decision fatigue
  • Chef-supported Mediterranean meals that support metabolic ease and calm evenings
  • Comfortable glamping accommodations built for sleep, recovery, and nervous system downshift

"I was feeling somewhat lost and disconnected from my creative potential. His compassionate and non-judgmental approach helped me shift my perspective. Instead of pushing for drastic changes, Oscar guided me to celebrate my journey so far and recognise the existing abundance in my life and in myself, a meaningful reframing that I am very grateful for. Thank you Oscar!"

Where You'll Be Staying

Can a place help you reset?

Costa del Soul is not a hotel and not a bootcamp.
It is a quiet, intentionally designed environment where your nervous system can downshift and regulate without effort.

You'll sleep in real beds, breathe fresh air, and experience natural light and silence.
Evenings are calm. Mornings are unhurried. The setting supports recovery and nervous system regulation naturally.

Choosing Your Format

All formats train the same core systems. The difference is time, pacing, and depth.

3-Day Focused Reset

Best for: First-time participants, busy schedules, or those who want a clear entry point into the protocols.

You'll get orientation, hands-on experience, and a framework to continue on your own. Ideal if you want to test the waters before committing to a longer format.

5-Day Deep Dive

Best for: Those ready for deeper physiological and nervous system adaptation.

More repetition, more integration, and stronger momentum. You'll experience meaningful change within a focused container while still maintaining some flexibility.

7-Day Full Immersion

Best for: Maximum reset, habit installation, and a clear long-term plan.

The most comprehensive option. Designed for full system reset with enough time to settle, practice, and integrate. Most participants choose this format once they understand the full arc of the work.

Not sure which format is right for you? Book a fit call and we'll discuss your goals, current situation, and help you choose the format that best supports where you are and where you want to go.

If ease, rhythm, and sustainability matter, Guaro is the place to begin.
