The half marathon is a favorite race distance for runners of all levels. Covering 13.1 miles, it requires a blend of speed, endurance, strategy, and mental toughness. Whether you’re aiming for your first finish or hoping to set a new personal best, there are proven ways to improve at the half marathon. In this guide, you’ll discover the best training strategies, pacing advice, strength and nutrition tips, and key mistakes to avoid for your best race yet.
Give Yourself Enough Time to Improve at the Half Marathon
One of the first steps to improve at the half marathon is allowing enough time for proper training. Most plans range from 10 to 16 weeks, depending on your experience and goals. A longer training cycle gives you more flexibility for recovery weeks, lets you absorb the work, and helps you adapt if life gets in the way. If you’re new to the distance or want to make significant gains, aim for the longer end of that range.
Vary Your Training
Doing the same workouts every week can stall your progress and make training feel monotonous. To truly improve at the half marathon, keep your training sessions varied. Mix in long runs, tempo runs, intervals, hill workouts, and easy recovery days. This not only keeps things interesting but also challenges your body in different ways, leading to better speed and endurance.
- Long runs build endurance and mental strength.
- Tempo runs improve your ability to sustain a faster pace.
- Intervals increase your speed and running economy.
- Hill repeats strengthen your legs and boost power.
Focus on Strength Training
Strength training is a game-changer for half marathoners. It improves running economy, increases power, and helps prevent injuries. Aim for two to three strength sessions per week, focusing on total-body movements like squats, lunges, deadlifts, and core exercises. Don’t forget single-leg moves like Bulgarian split squats and plyometric drills for balance and explosiveness.
Start strength training early in your plan and continue through your training cycle. As race day approaches, you can reduce the frequency but keep the intensity to maintain strength gains.
Prioritize Recovery
Improvement happens during recovery, not just hard workouts. Schedule at least one full rest day each week and listen to your body, especially in the final weeks of your plan. Incorporate easy runs and cross-training to allow your muscles to repair and adapt. Quality sleep and stress management are also crucial for optimal recovery.
Nail Your Nutrition
Nutrition is a cornerstone if you want to improve at the half marathon. Carbohydrates are your primary fuel source, so aim for 55–65% of your daily calories from high-quality carbs like whole grains, fruits, and starchy vegetables8. Protein supports muscle repair, so include lean sources at every meal. Healthy fats from nuts, seeds, and oils provide long-lasting energy.
During training, practice your race-day nutrition. Experiment with gels, chews, or sports drinks to find what works for you. On race morning, eat a familiar, easily digestible breakfast and start hydrating early.
Master Your Pacing Strategy
Pacing can make or break your half marathon. Many runners start too fast and struggle in the final miles. To improve at the half marathon, develop a pacing plan and stick to it. Use online pace calculators or your training data to determine your goal pace.
A proven strategy is to break the race into segments:
- First third: Run with your head—stick to your plan and avoid the adrenaline rush.
- Middle third: Run with your legs—settle into your rhythm and maintain focus.
- Final third: Run with your heart—dig deep and give your best effort.
Most experts recommend even splits or a slight negative split, where you run the second half at the same pace or a bit faster than the first11. Avoid weaving around runners in the early miles, as this wastes energy and adds distance.
Practice Race-Day Workouts
Incorporate race-pace workouts into your training to get comfortable running at your goal speed. Classic sessions include:
- 5–10 x 1 km at half marathon pace with short recoveries
- 8 x 3 minutes at a hard effort with 2 minutes jog or walk
- Tempo runs of 20–40 minutes at goal pace
These workouts teach your body and mind what race pace feels like, making it easier to execute your plan on race day.
Fuel and Hydrate Smartly
Develop a fueling strategy based on your training. Decide if you’ll carry water, rely on aid stations, or use a hydration vest1. Practice taking gels or chews every 30–45 minutes during long runs to avoid stomach issues on race day. Start hydrating several days before the race, and avoid trying new foods or drinks on race morning.

Warm Up Properly
A thorough warm-up prepares your body for the demands of race day. Jog easily for 5–15 minutes, do dynamic stretches, and add a few short strides at race pace. This routine raises your core temperature, increases blood flow, and primes your muscles for performance.
Common Mistakes to Avoid to Improve at the Half Marathon
- Starting too fast: Stick to your pacing plan and avoid the adrenaline trap.
- Neglecting strength training: Skipping the weight room can lead to injuries and slower times.
- Ignoring nutrition: Poor fueling sabotages your training and race performance.
- Skipping recovery: Overtraining without rest leads to fatigue and plateau.
- Not practicing race-day routines: Test your gear, nutrition, and pacing before race day.
