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.
If you are interested in finding someone to train with or getting a bit of coaching, check out the Training and Coaching Page.
Bridger Ridge Run 
I loved the training plan, thanks for sharing. Between picking up injuries when I run a lot of miles and other commitments training 3 times a week is perfect for me.
I just BQ’d yesterday with a 2:56 at the Sugarloaf Marathon up in Maine. I hit the wall pretty hard at mile 24 but luckily by then had a little spare time, walked for 1 min while I took on some fuel then finished it off. Not the finish I had in mind but just happy to go sub-3.
