Sub-4 hour marathon training plan (rules + paces)

Sub-4 is a pacing discipline problem first

Sub-4 doesn’t require “killer workouts.” It requires:

• easy days truly easy (so you recover)
• controlled quality (so it accumulates)
• long runs that are repeatable (so durability builds)

Sub-4 pace (and common goal paces)

Use this as a baseline (race-day conditions can change execution):

Tool:

• Running pace calculator

The readiness checklist (be honest)

Sub-4 is much easier when you already have:

• 3–5 runs/week consistently
• a long run that’s repeatable (not a weekly “test”)
• recovery that doesn’t collapse when life gets busy

Pick the right plan length (most people choose too short)

• 24 weeks: safest if consistency is your bottleneck (or you’re rebuilding)
• 20 weeks: solid default
• 16–18 weeks: only if your base and recovery are stable

Start here:

• 24-week marathon plan
• 20-week marathon plan
• 18-week marathon plan

The workouts that matter (simple)

1. One controlled threshold/tempo session
2. One long-run focus (easy with a controlled steady finish when recovered)
3. Everything else truly easy

The failure patterns (avoid these)

• turning easy runs into medium-hard runs
• adding speedwork to compensate for missed sessions
• racing long runs
