Train Smarter with Your Personalised Trail Running Coach

Personalised trail running training plans built around your fitness, your schedule and your races. Coaching that adapts to your feedback, week after week.

Trailia is an AI-powered trail running coaching platform that creates personalized training plans for trail runners of all levels. From beginners tackling their first 10K trail to ultra runners training for 100-mile races, Trailia uses AI, working inside a published set of training rules, to build science-based training plans adapted to your goals, fitness, and schedule.

What Trailia Does

  • Personalized AI Training Plans: A trail-specific training plan tailored to your goal race, schedule, experience level, and terrain, built from your actual Strava, Garmin or Polar history. Plans include running workouts, strength training, and cross-training.
  • Adaptive Training: Plans adjust weekly based on your completed workouts, training load, and feedback. Missed a workout? The AI rebalances your week.
  • Race Predictions: Fastest, most likely and slowest finish-time estimates for any trail race, from the course elevation profile and your last 12 weeks of training.
  • Race Fueling Plans: Segment-by-segment nutrition strategies built around your race course profile and rehearsed in training.
  • Injury Prevention and Recovery: AI-generated recovery plans, modified training during recovery, and injury-risk alerts from training-load analysis (ACWR, CTL, TSB).
  • AI Coach Chat: A coaching assistant that reads your plan, activities, goals and injury log before answering.
  • Device Integration: Automatic activity sync with Garmin Connect, Strava, and Polar Flow; manual FIT, GPX and CSV upload.
  • Strength Training: 46+ trail-specific strength exercises with video guidance.
  • Google Calendar Sync: Push your training plan directly to your calendar.
  • Trailia MCP: Connect your training data to ChatGPT, Claude or Cursor.

Who Is Trailia For

  • Trail runners preparing for a specific race (10K to 100-mile ultra)
  • Runners transitioning from road to trail
  • Athletes who want structured, science-based training without a human coach
  • Runners who use Garmin, Strava, or Polar watches

How the Coaching Works

Trailia writes plans with AI, inside coaching rules set by a CONI-recognised Level 1 Trail Running Coach: periodization toward the goal race, load that grows gradually and one channel at a time, regular recovery weeks, vertical and descent trained as their own skills, and a taper sized to the event. Every plan is checked against those principles before it reaches your calendar. The principles and the research behind them are at https://trailia.run/methodology.
