13.1 miles is a serious distance. It will test your aerobic base, your patience, and your ability to keep moving when your legs are begging you to stop. But it's also completely doable for almost anyone who's willing to train consistently for 10 weeks.
This guide walks you through everything: what a realistic beginner training schedule looks like, how to structure your long runs, what to do when you miss a session, and how to actually cross the finish line feeling strong — not destroyed.
Who this is for: You can run 3–4 miles without stopping, you've been running casually for at least a month, and you've signed up for your first half marathon (or you're seriously considering it). You don't need prior race experience.
Before the schedule, understand why it's built the way it is:
Most beginner plans try to do too much. Three quality runs per week — one easy, one moderate, one long — is enough to get you to the finish line. More than that and you're just adding injury risk without proportionate benefit.
Every other run exists to support the long run. The long run is where your body learns to go the distance. Don't skip it. Don't cut it short. If you can only fit in two runs in a week, make one of them the long run.
Your long runs should be conversational — you should be able to speak in full sentences without gasping. Most beginners run their easy runs too fast, accumulate fatigue, and end up injured by week 6. Run slower than feels necessary. You'll thank yourself later.
The plan below includes deload weeks — weeks where mileage drops intentionally. This isn't weakness. This is how you absorb the training and arrive at the start line healthy.
| Week | Run 1 | Run 2 | Long Run | Focus |
|---|---|---|---|---|
| 1 | 3 mi easy | 3 mi easy | 5 mi | Establish the habit |
| 2 | 3 mi easy | 4 mi easy | 6 mi | Build base |
| 3 ↓ | 3 mi easy | 3 mi easy | 5 mi | Deload — let body adapt |
| 4 | 4 mi easy | 4 mi easy | 7 mi | Push the long run |
| 5 | 4 mi easy | 5 mi easy | 8 mi | Build confidence |
| 6 ↓ | 3 mi easy | 4 mi easy | 6 mi | Deload — recovery week |
| 7 | 4 mi easy | 5 mi easy | 9 mi | New distance milestone |
| 8 | 4 mi easy | 5 mi easy | 11 mi | Peak long run approach |
| 9 | 4 mi easy | 4 mi easy | 12 mi | Peak week — biggest long run |
| 10 ↓ | 3 mi easy | 3 mi easy | Race Day 🏅 | Taper — arrive fresh |
Every run marked "easy" should be run at a truly easy effort. A simple test: if you can't hold a conversation, you're going too fast. Slow down until you can.
Easy pace for most beginners is 60–90 seconds per mile slower than they think they should be running. That's fine. The easy runs aren't about speed — they're about building aerobic base and recovering between long runs.
You will miss sessions. Here's how to handle it:
Your only job on race day is to not go out too fast. Here's how:
The one thing that will make or break your race: pacing. Run the first mile slower than feels right. Seriously. Almost every half marathon blowup starts in miles 1–3.
You don't need much. The essentials:
