So, you've run a 5K, maybe even a 10K, and now you're ready for something more challenging like a half marathon. Good for you! The half marathon is a great distance. It's long enough to feel challenged, but not so long that training for it completely consumes your life.
Below are a few good training tips for your first half marathon.
1. Build a base.
One mistake new runners often make when paring for a half-marathon is thinking that the 12- or 14-week plan takes you from the couch to the finish line. 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. If you have a solid base under your feet, then when you start your training, you'll only be acclimating to the demands of the half marathon training workouts.
If you have a weak base coming into the training, then you'll actually be asking your body to build that base while at the same time as acclimating to the new training demands. That's overtraining or an injury just waiting to happen.
2. Pick a plan.
Twelve weeks is a common length of many half-marathon training plans, however do a Google search and you'll find plans that range from 10 to 16 weeks. I prefer to use a longer plan (14 weeks) with my runners. The extra weeks allow for a little wiggle room if a runner gets sick or has slight set back or injury.

If 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). Study the various plans carefully before picking one. First, find one that meshes well with your work and family schedule.
If the plan has you running every day and you know that's not going to happen, then that plan is not for you. Second, find a plan that matches your running fitness level. If the first long run in the plan is 8 miles and your current longest run is 4, select a different plan.
Often plans are labeled for Beginner, Intermediate, and Advanced or Experienced, but even then, read through the plan carefully and make sure it fits your current running fitness level.
