20 Week Marathon Running Plan

20-Week Marathon Training Programme

Train with structure. Build your engine. Arrive at race day ready.

The AH Coaching 20-Week Marathon Training Programme is a progressive training plan designed to take you from your initial preparation phase all the way through to race day.

Rather than simply adding more miles each week, the programme combines easy aerobic running, long runs, marathon-pace work, half-marathon pace sessions, hill intervals, speed work and strength/cross-training to develop the fitness required for 26.2 miles.

What’s included:

• ✅ Full 20-week structured programme
• ✅ Progressive weekly running schedule
• ✅ Marathon Pace (MP) training
• ✅ Half Marathon Pace (HMP) sessions
• ✅ 5K & 10K pace intervals
• ✅ Hill interval workouts
• ✅ Progressive long runs
• ✅ Marathon simulation sessions
• ✅ Strength & cross-training days
• ✅ Dedicated 2-week taper
• ✅ Clear pace guide and session breakdowns
• ✅ Professionally designed downloadable PDF

The programme progresses through four key phases:

Preparation → Half Marathon Development → Marathon Specific Training → Taper & Race Day

Ideal for runners who want more than simply completing miles and want a clear, progressive structure to improve endurance, strength, pacing and race-day confidence.

20 weeks. One goal. 26.2 miles.
