Running a full marathon can be intimidating. Training for a half marathon is a great stepping stone for the next level, beyond a 10K. A half marathon is 13.1 miles or a 21K and is more achievable than one might imagine. Preparing for this is no different than training for a full marathon with the only exception being distance ran.
Utilizing training programs, which gradually progress running distance and provide rest days or relative rest days, is essential. This prevents excessive stress to your body and breakdown of tissue, allowing for rebuilding and recovery. Training programs vary considerably. Identify the training program that is right for you, as some are built for novices and some for advanced experienced runners.
Strength training and cross training are helpful to add to your preparation/training program. Addressing weakness or faults will help make running more efficient and can prevent potential injuries. Mixing up your exercise, whether it is weight lifting, aerobics, or plyometric training, helps build muscles and adds durability to the body and its tissues.
Below is an example of a Half Marathon Training Program. This can be used as a guide to advance mileage safely and incorporate strength and cross training into your routine.
