The Fairy Poet and the Marathon

I am registered to run the L.A. Marathon on 15 March 2015.  My basic training schedule is 3 RUNS per week, 2 BIKES per week, and 1 HIKE per week.  I may replace some runs with ELLIPTICALS during the severest of weather conditions.  I will be as Plant-Based as possible from November 1st through March 15th. I am reading No Meat Athlete by Matt Frazier for inspiration and tips.  I will train without music (except on elliptical machines because gyms are just too boring).   I want to be as time efficient in my training as possible because I will be doing theater through Dec. 17th, and I am seriously on the job-hunt (I accepted a new job on 12/08/14.  I start on 12/15/14).  Below is my exercise log, so you may track, if you wish, my activities, successes and failures.  My goal is to run the Average Joe Marathon below four hours...3:45 would be nice!
