3 Tips for Improving Your Half Marathon Time
So, how do you improve your half marathon time? Here’s where your fitness level comes in. By training, you can train your body to run faster for longer and improve your half marathon time.
Here are three tips to improve your half marathon time:
#1: Perfect Your Pacing
The half marathon is a test of not only your aerobic fitness and endurance but also your patience. If you blast off the starting line, you’ll run out of steam before the end of the race. Therefore, pacing yourself appropriately is vital to running a good half marathon.
Research shows that most runners follow a more even pacing strategy in the half marathon compared to the marathon, which is best for optimal performance.
By running even splits, you’ll keep your effort level below your lactate threshold, preventing the buildup of metabolic waste products that induce that dreadful burning, heavy legs feeling, and intense fatigue.
Improve your pacing by training at race pace and dialing into your anticipated pace so often that it feels natural. Tempo runs, threshold runs and even long runs can have a few miles at race pace.
Additionally, use your watch to guide your pace. The effort at the beginning of a race often feels far easier than the pace you’re actually running because of all the adrenaline and excitement.
If you’re planning to run a 1:51:15 half marathon, for example, make sure you’re hitting the mile mark around 8:25.
#2: Hit the Gym
Strength training helps you build muscular strength and power and correct imbalances, enabling you to run more efficiently. It can also help prevent injuries, allowing you to train consistently, which is the key to progress.
Be sure to include strength training into your plan twice a week to assure you’ll reap all of the benefits.
#3: Follow a Training Plan
A training plan gives you structure and consistency and ensures your workouts are effective for the demands of the half marathon. Use a reputable half marathon training plan that not only works with your schedule and lifestyle but also excites you and looks motivating.
