Trail Running Training Plan: From First Trail to 50K
Prepare your trail race with a structured plan combining elevation, endurance and strength training
Prepare my trailTrail running means running in nature, on paths with elevation gain. Whether you're preparing for your first 15K trail or a 50K ultra, training requires a specific approach: strength training, hill work, effort management on varied terrain, and adapted nutrition. RunRun offers a flexible 12-week plan to approach your trail with confidence.
Pourquoi choisir RunRun ?
Elevation training
Elevation is the key to trail running. The plan includes hill sessions, hiking-pace climbs, and technical descents to prepare your legs.
Strength training
2 strength sessions per week: core work, squats, lunges, proprioception. Essential to handle elevation and prevent injuries.
Varied terrain endurance
Long runs are done on trails, not roads. You learn to manage effort on constantly changing terrain: climbs, descents, flats, technical sections.
Effort management
In trail running, think in time, not distance. Walking uphill is normal and part of the strategy. Heart rate guides your pace.
Specific sessions
Short explosive hills, long power climbs, technical descents. Each session works a key trail running skill.
Adaptable plan
The plan covers 3 goals: first trail (15-20K), medium trail (30K), ultra-trail (50K). Choose your distance.

Tips to succeed on your trail
Walk the uphills
Even elites walk steep uphills. Use active hiking with hands on thighs. You save energy for later.
Train on race-like terrain
If possible, preview the course or train on similar terrain. Every trail is unique: rocks, roots, mud, grass.
Carry the right gear
Hydration pack, trekking poles (if allowed), windbreaker, headlamp for ultras. Check mandatory gear list for your race.
Manage your nutrition
In trail running, eat regularly: every 30-45 min. Bars, gels, dried fruit, energy chews. Test everything in training, never on race day.
Respect the descents
Descents destroy quadriceps. Train to descend fast and technical. Short quick steps, low center of gravity, eyes looking ahead.
