Starting a marathon can be an exciting and rewarding challenge for beginner runners. To help you succeed, we’ve created the ultimate 12-week training schedule designed specifically for beginners. This plan gradually builds endurance, strength, and confidence, ensuring you’re well-prepared for race day.

Week 1-4: Building a Foundation

During the first four weeks, focus on establishing a running routine and developing basic endurance. Keep your runs comfortable and avoid overexertion. Incorporate rest days to allow your body to recover.

  • Week 1: 3 runs (20-30 minutes each), 2 rest days
  • Week 2: 3 runs (30 minutes each), 2 rest days
  • Week 3: 3 runs (35 minutes), 1 cross-training day, 1 rest day
  • Week 4: 3 runs (40 minutes), 1 cross-training day, 1 rest day

Week 5-8: Increasing Mileage

In these weeks, you’ll start increasing your weekly mileage and introducing longer runs. This helps your body adapt to longer distances and prepares you for race day. Continue to listen to your body and avoid pushing too hard.

  • Week 5: 3 runs (45 minutes), 1 long run (start at 5 miles), 1 rest day
  • Week 6: 3 runs (50 minutes), 1 long run (start at 6 miles), 1 cross-training day
  • Week 7: 3 runs (55 minutes), 1 long run (7 miles), 1 rest day
  • Week 8: 3 runs (60 minutes), 1 long run (8 miles), 1 cross-training day

Week 9-12: Peak Training and Tapering

The final phase focuses on reaching peak mileage and then tapering to allow your body to recover before race day. This is crucial for optimal performance and injury prevention.

  • Week 9: 3 runs (60 minutes), 1 long run (10 miles), 1 rest day
  • Week 10: 3 runs (55 minutes), 1 long run (11 miles), 1 cross-training day
  • Week 11: 2 runs (50 minutes), 1 long run (8 miles), 1 rest day
