The 3-to-1 Week Progression

Most effective progression: 3 weeks build, 1 week recovery

Week 1: Build    ████████ (40 miles)
Week 2: Build    ██████████ (45 miles)
Week 3: Build    ███████████ (48 miles)
Week 4: RECOVERY ██████ (32 miles) ← Down week
Week 5: Build    ██████████ (45 miles)
Week 6: Build    ███████████ (50 miles)
Week 7: Build    ████████████ (53 miles)
Week 8: RECOVERY ███████ (38 miles) ← Down week

Why this works:

Allows adaptation from previous 3 weeks
Prevents cumulative fatigue
Reduces injury risk
Mental break from building

Quick Decision Guide

"What phase am I in?"

No goal race yet? → BASE phase

Build aerobic foundation
Increase mileage gradually
80%+ easy running

12-20 weeks until race? → BUILD phase

Add tempo runs (1x/week)
Maintain volume
Build lactate threshold

6-10 weeks until race? → PEAK phase

Add intervals (every 7-14 days)
Race-specific work
2 quality sessions/week

1-3 weeks until race? → TAPER phase

Cut volume 30-50%
Maintain some intensity
Prioritize rest

Just raced? → RECOVERY phase

Easy running only
2-4 weeks off hard training
Let body repair

Common Periodization Mistakes

❌ Skipping base phase → Jumping to hard workouts without foundation ✅ Build base first → 12-16 weeks minimum

❌ No recovery weeks → Building indefinitely without down weeks ✅ 3 build, 1 recovery → Every 4th week reduce volume 20-30%

❌ Constant intensity → Always doing hard workouts ✅ Progressive phases → Build intensity gradually over months

❌ Inadequate taper → Training hard until race week ✅ Proper taper → Reduce volume 30-50% for 1-3 weeks

❌ No off-season → Racing and training hard year-round ✅ Planned recovery → 2-4 weeks easy after goal races

Key Principles

Volume before intensity → Build mileage base before adding hard workouts
Progressive overload → Gradually increase stress over time
Recovery weeks essential → Down weeks allow adaptation
Race-specific training → Peak phase matches race demands
Taper = trust your training → Less is more in final weeks

Remember: Periodization isn't just a fancy plan - it's how you systematically build fitness while avoiding injury and overtraining. Every elite runner uses periodization. You should too.
