Marathon | 14-Week Intermediate Performance Plan
Moving to the marathon distance requires a shift in how you view recovery. This 14-week program provides the professional structure needed to build endurance and speed without training impacting your professional life. By replacing unstructured miles with sessions that have a clear goal, you ensure every run contributes toward a successful result.

A core feature of this plan is the broken long run stimulus. Rather than one high-risk session, your endurance volume is spread over two or three days. This provides the cumulative fatigue needed for adaptation while ensuring you stay fresh for midweek speed sessions. This framework removes training uncertainty, letting you focus on execution while managing a busy schedule.
The Benefits of Split Long Runs
- Adaptation: Gain endurance by running on tired legs, mimicking the final miles of a marathon.
- Consistency: Less damage from a single massive run means less recovery and more training.
- Injury Mitigation: Spreading volume lowers the risk of stress-related injuries.
- Quality: You remain fresh enough to hit target intensities in midweek speed sessions.
How This Helps You
- Direction: A professional schedule that tells you exactly what to do each day.
- Pacing: Guidance on managing effort to sustain target speed throughout the race.
- No Guesswork: Every workout is prescribed using your personal targets.

Your 14-Week Roadmap
- Weeks 1-4: Baseline fitness and foundational stamina.
- Weeks 5-7: Training volume increase and race-pace efforts.
- Weeks 8-12: Speed development at and above race pace.
- Weeks 13-14: Recovery through a taper to ensure you are fresh.
Is This Your Next Step?
