— Manifesto
Three things we don't do.
02
We don't track weight.
No scale. The metric is: did you climb the trail breathing through your nose? Did you lift 10 kg more without cheating?
03
We don't sell supplements.
Pablo designs your nutrition plan, he doesn't sell you creatine. If you need it, we'll tell you which brand to order online.
The mountain doesn't judge you.

What the ones who come back say.
«I went from not being able to climb Gibralfaro without stopping to finishing my first 50 km ultra. Iván pulled me off the crazy cardio I was doing on my own and built something that would last.»
Mateo R.
· 50 km ultra trail
«I was 41, overweight and living with chronic back pain. Helena taught me to lift heavy without hurting myself. Today I deadlift with my whole body.»
Carmen V.

«As a licensed cyclist I thought the gym would take power away from me on the bike. I gained 18 W on my FTP in 12 weeks. I shut up and came back.»

— Before you start
Five common questions.
- 01
- 02
- 03
- 04
- 05
Do I need to have run before?
No. Trail Base exists for exactly this. We start with 25 minutes of easy jogging on flat ground and build up based on your body and schedule. The only requirement is being able to walk 60 minutes straight without stopping.
What if I travel or get injured?
The plan adapts. Each week is published on Monday and we can rewrite it if you tell us 48 h ahead. Serious injuries: free pause, and we resume when your doctor clears you.
Do you have a facility or just the mountain?
A 220 m² studio in an industrial park with racks, kettlebells and a weightlifting platform. Three weekly sessions take place in the mountains (Almogía / Torcal / La Concha).
Can I train only on weekends?
That's not our profile. The program needs 3-6 sessions a week to work. If weekends are all you have, we'll recommend a personal-plan coach — no referral fee.
Is nutrition included?
Nutrition plan included in Hybrid Power and Backcountry. In Trail Base it's optional (+€80/month). Pablo works from your real mileage, not from the scale.
— Ch. VII · The call
15 minutes. No pressure.
A call to understand what you run, what's held you back and where we start. If we're a fit, we talk program. If not, we'll point you to someone better — free of charge.
