Thanks for writing to us. This sounds like a fun but very demanding run. You are wise to push this out a year to give you a chance to build up the kind of running strength needed to complete it without injury. Starting with our marathon plan would be a good place to begin. It will teach you how your body responds. But, for the specific demands of this mountain run you should consider either the Via Valas or Mike Foote plans as the next step. Since you have a full year I think doing these plans back to back (with a 2-3 week break between them) will give you the best results.
