How much should you train if you want to run a good half marathon? There are two distinct types of runners who ask this question: the first-time half marathon runner who runs just 2 to 3 days a week for 3 to 5 miles.
All half-marathon training plans that range in length from 10, 14 or 16 weeks assume that you've already built a weekly mileage base of at least 15-20 miles. Your longest run should also be at least 5 miles.Anything less than this weekly mileage or longest run mileage will overwhelm your body's ability to acclimate.f this is your first half-marathon, I strongly recommend a plan longer than 10 weeks. This will give you more time to acclimate to the training demands. Not only do the plans vary in length, they also vary in content (the types of workouts, weekly mileage, and the number of times you run each week).
