Half Marathon Training Tips & Frequently Asked Questions

How To Train For A Half Marathon

Slowly add mileage to increase your base – an easy-to-follow rule is to increase your long run by one mile every 1-2 weeks and take a rest day in its place every month. The slow increase as well as not “always increasing” allows your body ample time to recover.

Half Marathon Training Nutrition

Aside from the running, nutrition might just be the most important part of your half marathon training plan. Half marathon nutrition is everything from what to eat the week before your half marathon, to the best snacks, to the best meals, to fueling during your half marathon.

Our Recommended Training Apps

For keeping track of your mileage, pace, and progress we recommend Strava which has a seamless user interface and great community support features. For more comprehensive and dynamic running plans that respond to each training session, we recommend Runna. Half Marathon Guide readers get 2-weeks free with code HALFMARATHON.

Injury Prevention for Half Marathon Runners

If done too quickly or with improper form, increasing mileage and speed can result in injuries – from shin splints to runner’s knee and beyond. The most important factor in completing any training plan is staying consistent. In addition to following a half marathon training plan, it’s important to include structured strength training you can do yourself or follow a guided strength training program. You can find examples of reliable injury prevention programs online or by downloading free apps like Exakt Health.

Strength Training for Half Marathon Runners

Every beginner half marathon runner should be incorporating strength training and cross training. Both are required for reducing overuse injuries, building speed, endurance, and stability. On any non-running day in any of our training plans, you should be incorporating one or the other.

Why the Long Run is Your Most Important Training Run

Speed work and tempo runs get you faster. Recovery runs keep you from getting injured. Shorter races prepare you for the overall experience. But the long run is the most important element in making it to the finish line feeling great. When embarking on any long run journey you’ll also need a nutrition strategy.


Whether you are a beginner looking to run for the first time, a runner returning from an injury or break, or simply a runner starting a new half marathon training plan, it can take weeks before the habit forms. Once you stick with the plan for 4-8 weeks, however, it begins to feel normal to lace up and run a few (or more) times a week.
