How This Training Plan Generator Works
Our running training plan generator creates personalized, periodized plans based on proven coaching methodologies. Here's what makes it effective:
Periodization Principles
Every plan follows a structured periodization model with four phases:
- Base Phase: Build aerobic foundation with easy volume (80-85% easy effort)
- Build Phase: Introduce quality workouts while maintaining volume
- Peak Phase: Race-specific training at highest volume
- Taper Phase: Reduce volume while maintaining intensity for race readiness
80/20 Training Philosophy
Following the 80/20 endurance training principle, approximately 80% of your training is at easy effort (RPE 3-4) and 20% at moderate to hard effort. This approach:
- Maximizes aerobic development
- Reduces injury risk
- Allows for proper recovery between hard sessions
- Is backed by research on elite athletes
Recovery Weeks
The plan automatically includes recovery weeks every 3-4 weeks (depending on your fitness level) where volume is reduced by approximately 35%. This allows your body to adapt and grow stronger.
Ultra-Specific Features
For ultramarathon distances (50K and beyond), the generator includes:
- Back-to-back long runs: Running long on consecutive days to simulate race fatigue
- Extended time on feet: Focus on duration over pace
- Appropriate taper length: Longer tapers for longer races
RPE-Based Intensity
Instead of prescribing specific paces (which vary by individual), this plan uses Rate of Perceived Exertion (RPE):
- RPE 3-4 (Easy): Conversational pace, can speak in full sentences
- RPE 5 (Moderate): Slightly harder, can speak in shorter phrases
- RPE 6-7 (Tempo): Comfortably hard, limited conversation
- RPE 8-9 (Hard): Hard effort, only a few words at a time
