Sub 2 Hour Half Marathon Pace: Training Tips and Split Strategy
Breaking 2 hours in the half marathon is a milestone goal for many recreational runners. It requires consistent training, smart pacing, and mental toughness. But with the right strategy, it's absolutely achievable.
In this guide, we'll break down exactly what pace you need to run sub-2, provide detailed split strategies, and share training tips from runners who've successfully broken this barrier.
What Pace Do You Need for a Sub 2 Hour Half Marathon?
To finish a half marathon in under 2 hours (1:59:59), you need to maintain an average pace of:
Target Pace: 9:09 per mile (5:41 per km)
This gives you exactly 1:59:59 for the 13.1-mile distance
However, most successful sub-2 runners actually target a slightly faster pace to build in a cushion:
- 9:00 per mile (5:35 per km) → 1:57:51 finish
- 9:05 per mile (5:38 per km) → 1:58:56 finish
Mile-by-Mile Split Strategy for Sub 2 Hour Half Marathon
Here's a detailed mile-by-mile pacing plan targeting a 1:58:00 finish (9:00/mile average):
| Mile | Target Time | Cumulative Time |
|---|---|---|
| Mile 1 | 9:10 | 9:10 |
| Mile 2 | 9:05 | 18:15 |
| Mile 3 | 9:00 | 27:15 |
| Mile 4 | 9:00 | 36:15 |
| Mile 5 | 9:00 | 45:15 |
| Mile 6 | 9:00 | 54:15 |
| Mile 7 | 9:00 | 1:03:15 |
| Mile 8 | 9:00 | 1:12:15 |
| Mile 9 | 9:00 | 1:21:15 |
| Mile 10 | 9:00 | 1:30:15 |
| Mile 11 | 8:55 | 1:39:10 |
| Mile 12 | 8:50 | 1:48:00 |
| Mile 13 | 8:45 | 1:56:45 |
| Final 0.1 | 0:52 | 1:57:37 |
Note: This strategy starts conservatively and finishes strong (negative split), which is ideal for preventing burnout.
Are You Ready for Sub 2?
Before attempting a sub-2 hour half marathon, you should be able to:
- Run a 10K in under 55 minutes comfortably
- Complete a 10-mile training run at 9:15-9:30 pace
- Have a weekly mileage of 25-35 miles consistently
- Maintain 9:00 pace for 8-10 miles during training
If you can check these boxes, you're ready to train seriously for sub-2!
12-Week Training Plan Highlights for Sub 2 Hour Half

Key Workouts for Sub 2 Success
1. The Goal Pace Long Run
Run 10-12 miles with the last 6 miles at 9:00 pace. This teaches your body to hold goal pace on tired legs.
2. Tempo Threshold Runs
6-8 miles at 8:30-8:45 pace. This builds the lactate threshold you need to sustain sub-9 pace.
3. Yasso 800s
Run 8-10 x 800m at 3:58-4:00 (goal half marathon time in minutes/seconds). This classic workout is a great predictor.
4. Race Simulation
4 weeks out, run a 10K race or time trial at your target effort. You should finish around 53-55 minutes.
Race Day Tips for Breaking 2 Hours
Pre-Race Preparation
- Carb Load: 2-3 days before, increase carbs to 60-70% of calories
- Hydration: Drink consistently in the days leading up, not just race morning
- Sleep: Prioritize sleep 2 nights before (race eve nerves are normal)
- Race Kit: Test all gear in training—nothing new on race day
During the Race
- Start Controlled: The first mile should feel EASY. If you're breathing hard at mile 2, slow down
- Fuel Early: Take your first gel or energy at mile 4-5, then every 45 minutes
- Water Stations: Drink 4-6 oz every 2-3 miles, don't skip hydration
- Mile 10 Push: This is where you either lock in or fall apart. Stay mentally tough
- Final 5K: Empty the tank. You should have nothing left at the finish
Common Mistakes That Prevent Sub 2
1. Starting Too Fast
Many runners go out at 8:45 pace and blow up by mile 8. Patience in the first 3 miles is critical.
2. Not Training at Goal Pace
You need to log miles at 9:00 pace during training. Your body needs to know what this feels like.
3. Inadequate Weekly Mileage
Running only 15-20 miles per week won't build the endurance for 13.1 at pace. Aim for 30+ miles weekly.
4. Skipping Speed Work
Long slow distance alone won't get you to sub-2. You need interval training to build leg speed.
