Right now, it is early March and the Ridge Run in August may seem a long ways away. Nevertheless, if the 2015 Ridge Run is in your plans, it is time to start dedicating a little time and effort to training.
As a minimum, 3 to 4 hours a week of endurance and strength (hills) training are needed to maintain and build a base of preparation. Remember, this blog has lots of advice on training. A good place to start is the Training and Preparation section of the Best Of Page.
