Taking part in a half marathon is a good test of your fitness and stamina as you push your body to its limits trying to achieve a personal best.
Running just over 13 miles cannot be achieved in a day unless you want an injury of some kind. You should follow a strict training plan to reach this target safely and healthily. Your training plan should start by easing you into shorter runs at a steady pace, the distance and effort levels will begin to increase over time. Training for a half marathon can safely be achieved in 12 weeks if you are already a relatively fit person.
A great way to train for a half marathon is by getting a friend to join you in the race and with the training too. This is a good training tactic as you will be able to support each other and spur each other on.
