If you’re thinking about running a half marathon, you may be wondering, How long does it take to train for a half marathon?
Your training period for a half marathon race (13.1 miles) depends on numerous factors, including your current fitness level, your running experience, and your goals for the race.
Beginner runners who have never done a half marathon before should plan to train anywhere from 10 to 16 weeks, depending on their starting point. Taking a gradual approach will help you safely and comfortably progress with your training and avoid running injuries.
Most experienced runners who have already run a 5K or other race may be ready to run a half marathon with six to eight weeks of preparation. But if they’re hoping to beat a personal record, they should plan on dedicating 10 to 12 weeks to half marathon-specific training.
If you’ve been running or run/walking for a few months and you’ve already tried a shorter race distance, such as a 5K, you’re probably ready to start training for a half marathon.
Here’s an estimate of the time commitment to expect with half marathon training, based on your starting point, and some training schedules so you can see what the training looks like:
Half Marathon Training Plans for Beginner Runners
If you’ve never run a half marathon and you’re currently running under 10 miles each week, expect to spend 12 to 14 weeks preparing for your half marathon. You should plan on running at least three times a week in the beginning, and at least four times a week as your training progresses. You’ll also want to incorporate 1-2 days of cross-training to help build your fitness and boost your injury resistance.
In terms of the weekly time commitment, the highest mileage weeks of your training will be three, four, and five weeks before your race. During the final two weeks before the half marathon, you’ll start dialing your mileage down during your tapering phase.
