About TRUNK
Trail Running Unlocks Natural Knowledge.
Our Mission
Trail running is the most natural form of human movement, encoded in our DNA. TRUNK connects this primal bond with nature to cutting-edge performance science, making elite training knowledge accessible to every runner who aspires to unlock their potential by following the 'Trail by Feel' philosophy.
Philosophy
“Discover yourself through nature. Know yourself through science.”
TRUNK embodies the fusion of two fundamental passions: the raw beauty of natural landscapes and the elegant precision of scientific methodology. We believe trail running is a dance between the athlete and the terrain, demanding both physical excellence and intuitive understanding. Our platform blends proven periodization strategies with the 'Trail by Feel' philosophy, creating adaptive plans that honor both your body's wisdom and objective performance data.
Core Components
AI Assistant 5NA1L
Your intelligent training coach. 5NA1L analyzes your training diary, season plans, and performance data to provide personalized insights and recommendations.
Trail by Feel Intelligence
Learn to interpret your body's signals—Heart Rate Variability (HRV), sleep quality, energy levels—to make smart training adjustments. This isn't guesswork; it's developing the athlete's key skill of self-awareness, backed by data from your wearables.
Adaptive Periodization
Dynamic training blocks that automatically adjust to your race calendar and performance data. We build a strong foundation, then surgically prepare for a specific event, ensuring you peak when it matters most.
Our Vision
TRUNK is meant to be the lab where trail runners plan seasons, monitor biomarkers, and get guidance without juggling tools. Diary stays the source of truth, planner is the hypothesis, and 5NA1L connects them responsibly.
Growth Model
Nature Layer
Diary, planner, and metabolism stay free — they teach athletes to feel load before chasing watts.
Science Layer
Pro tiers will unlock larger AI quotas, hardware integrations, and deeper analytics without compromising data control.
