Plan Description

This 12-week training plan is built for beginner trail runners aiming to complete a 15–25K trail race. It’s ideal if you:

- Can comfortably run 5K

- Want to explore trail running without overtraining

- Prefer a manageable schedule with just 3 runs per week

- Appreciate structure, progression, and recovery

- Value quality over quantity in your training

- The plan is written using UESCA coaching principles, with a strong focus on gradual progression, varied and sustainable training habits.

What to Expect:

- Clear, structured workouts delivered via the TrainingPeaks app

- Detailed guidance for each session: effort cues (RPE), terrain suggestions, mindset tips

- Recovery and taper weeks built in

- Optional cross-training for flexibility

- Weekly focus areas to keep you motivated and on track

- No need to obsess over pace, heart rate, or gear, this plan is effort-based and accessible

Communication:

This is a self-guided plan. You won’t receive direct coaching, but the workouts are written as if your coach is right there with you. If you’d like to upgrade to personal support or video feedback, options are available.

What You’ll Need:

- Trail running shoes

- Access to trails or parks with some variation in terrain

- A GPS watch or smartphone app (optional but helpful)
