Questions and answers

Who is this training plan for?

This program is for you if you are a runner who has not completed a half marathon.

Would you like me to take the rest days?

Yes, it is essential to rest and recover for the body to become accustomed to training and injury prevention. Rest days reduce your risk of injury.

What kinds of cross-training would you recommend?

Weight lifting, strength training, spin class, or any other activity that you find appealing.

Is walking OK during training?

Absolutely. You should take walking breaks to keep your heart rate in the correct heart rate zone. Adding a walking break during the run helps build endurance on training runs. It is up to you to run or walk the whole distance. The important part is maintaining a conversational pace within the distance of the long run or long run.

Do I need special shoes?

You should purchase running shoes at a running store where they can analyze your run form and stride. The wrong shoes will lead to a miserable experience.

Why does the last week contain fewer training sessions?

The last week of training is a taper week. The final week backs off the training time, fully allowing you to recover on race day.
