12-Week Beginner’s Half Marathon Plan: From Couch to Finish Lin

12-Week Beginner’s Half Marathon Plan: From Couch to Finish Lin

Training for your first half marathon (13.1 miles/21.1km) is an achievable goal with the right plan—no prior running experience needed! This half marathon training guide focuses on gradual progression, cross-training, and nutrition tips to build endurance training safely, so you cross the finish line strong and injury-free.

Weekly Structure: 4 Days of Training + 3 Days of Recovery

  • 3 Running Days: 1x easy run, 1x long run, 1x cross-training or strength.
  • 3 Recovery Days: 1x rest, 1x gentle cross-training (yoga, walking), 1x core/strength.
  • Key Principle: Follow the 10% rule—never increase weekly mileage by more than 10%.

Phase 1: Base Building (Weeks 1–4)

Goal: Build consistency, improve running economy, and adapt to training.

Weekly Focus

  • Run-Walk Intervals: Start with 1 minute running + 1 minute walking to avoid burnout.
  • Cross-Training: 1 day of cycling, swimming, or elliptical to boost cardio without impact.

Sample Weekly Plan

Day Activity Details
Monday Easy Run 20 minutes (run-walk: 1:1), Zone 2 effort
Tuesday Strength Training Core (planks, glute bridges) + leg exercises
Wednesday Cross-Training 30 minutes cycling or swimming
Thursday Easy Run 25 minutes (run-walk: 2:1), focus on form
Friday Rest or Yoga Active recovery
Saturday Long Run 30 minutes (run-walk: 3:1), add 5 minutes weekly
Sunday Rest or Gentle Walk 20 minutes recovery walk

Nutrition Tips

  • Hydration: Drink 3L water daily; add electrolytes for runs over 45 minutes.
  • Post-Run Fuel: 20g protein + 50g carbs within 60 minutes (e.g., Greek yogurt + banana).

Phase 2: Endurance Building (Weeks 5–8)

Goal: Increase long run distance, introduce steady-state pace.

Weekly Focus

  • Long Run: Gradually build to 90 minutes by Week 8 (no more than 25% of weekly mileage).
  • Pace Training: Run easy days at a conversational pace (Zone 2).

Sample Weekly Plan

Day Activity Details
Monday Easy Run 35 minutes (run-walk: 5:1 or continuous jog)
Tuesday Strength Training Add resistance bands for glutes/hips
Wednesday Cross-Training 45 minutes low-impact cardio (elliptical)
Thursday Steady Run 40 minutes at easy pace, focus on posture
Friday Rest or Yoga Foam rolling to release tight muscles
Saturday Long Run 60–90 minutes (e.g., Week 5: 60 mins, Week 8: 90 mins)
Sunday Active Recovery 30 minutes walking or gentle cycling

Nutrition Tips

  • Carb Loading (Weekly Long Run): Eat 1g/kg carbs 2 hours pre-run (oatmeal + honey).
  • In-Run Fuel: For runs over 75 minutes, take 1 gel (20g carbs) at the halfway point.

Phase 3: Intensity & Adaptation (Weeks 9–11)

Goal: Improve pace sustainability, simulate race conditions.

Weekly Focus

  • Tempo Runs: 2x10 minutes at 75% max heart rate (Zone 3) to build lactate threshold.
  • Race Simulation: Practice fueling/hydration during a 10-mile long run.

Sample Weekly Plan

Day Activity Details
Monday Tempo Run 10-minute warm-up, 2x10 mins tempo, 10-minute cool-down
Tuesday Strength Training Full-body workout (squats, push-ups, planks)
Wednesday Cross-Training 60 minutes cycling or swimming, steady pace
Thursday Easy Run 45 minutes at Zone 2, focus on recovery
Friday Rest or Yoga Prioritize sleep (7–9 hours)
Saturday Long Run 10–11 miles at race goal pace (e.g., 9:30/mile)
Sunday Active Recovery 40 minutes walking + core exercises

Nutrition Tips

  • Protein Intake: 1.2g/kg body weight daily (chicken, fish, lentils) to preserve muscle.
  • Hydration Strategy: Drink 150–300ml every 30 minutes during long runs with electrolytes.

Phase 4: Taper & Race Week (Week 12)

Goal: Reduce fatigue, maintain fitness, and prepare mentally.

Weekly Focus

  • Mileage Cut: Reduce by 40% (e.g., Week 11: 30 miles → Week 12: 18 miles).
  • Final Prep: Test race gear, practice transitions (e.g., fueling on the go).

Sample Weekly Plan

Day Activity Details
Monday Easy Run 30 minutes at easy pace, no intensity
Tuesday Rest or Yoga Focus on mobility drills (hip openers)
Wednesday Cross-Training 30 minutes cycling or walking, very easy
Thursday Easy Run 20 minutes, simulate race morning routine
Friday Rest & Gear Check Lay out race day items (shoes, gels, watch)
Saturday Race Day! 1–2 mile warm-up, start 保守,finish strong
Sunday Recovery Walk 20 minutes gentle movement, celebrate!

Nutrition Tips

  • Pre-Race Dinner (2 Days Out): High-carb meal (pasta, sweet potatoes) + moderate protein.
  • Race Morning: Light breakfast 2–3 hours pre-race (toast + peanut butter, banana).

Key Strategies for Success

1. Cross-Training for Injury Prevention

  • Best Options: Swimming (full-body recovery), cycling (leg strength without impact), yoga (improves mobility).
  • Frequency: 1–2 days/week to reduce joint stress and build balanced fitness.

2. Nutrition for Sustained Energy

  • Daily Diet: 50% carbs (oats, rice), 25% protein (eggs, tofu), 25% healthy fats (avocado, nuts).
  • Avoid New Foods: Test gels/barbs in training to prevent gut issues on race day.

3. Recovery is Non-Negotiable

  • Rest Days: Use a sports watch to track resting heart rate—skip a workout if RHR is 5+ BPM higher than usual.
  • Sleep Quality: Aim for 7–9 hours; use sleep tracking to ensure deep recovery stages.

4. Gear Essentials

  • Running Shoes: Neutral or stability shoes (tested for 50+ miles to avoid blisters).
  • GPS Watch: Track mileage/pace (e.g., EZON GPS Series for accurate route mapping and heart rate monitoring).
