The focus is on a steady and sustainable build-up, helping you develop endurance, strength, and trail efficiency — finishing strong and injury-free.

Running sessions are prescribed by time and heart rate zones (not distance), ensuring each workout adapts to your current fitness.
Includes strength, mobility, and stretch workouts with clear guidance and video support.
The structure prioritizes gradual adaptation and balanced recovery to reduce overtraining risk and prepare you for long-term success.
