After I moved my marathon date to February I lost all motivation to run. I dropped my plan to run a marathon and to log 1000 miles in 2012. I decided to cut back to running 1 day a week for 2 miles with my dog but even that plan did not last. After 15 months I stopped but I did manage to sign up for an 18km trail run with my father-in-law and his friend. It is on December 8th and I have done zero training for it until last Friday. I ran, hiked, and climbed 8.3 miles with my father-in-law in Palo Duro Canyon (the second largest canyon in North America). It gave me confidence I can manage 11ish miles but I have not run in the past 6 days.
My loss of desire to run was match with an increased focus of strength training. After taking 11 days off of lifting I started the StrongLifts 5x5 program. It is a very simple 3 day a week routine. You alternate doing 5 sets of 5 reps (after some warm up sets) of three full body exercises. Working A you do Squats, bench press, and bent over barbell row.  Workout B you do Squats, Overhead Press (standing), and Deadlifts. In order to develop proper form you start with just an Olympic (45 pound) barbell and 5 pounds each exercise the next workout (10 pounds on deadlifts). I had been neglecting working my legs the past 2 years and I am loving it.
As an experiment the first 4 weeks of SL5x5 I also followed the GOMAD (Gallon of Milk a Day) Diet. Basically you drink a gallon of whole milk on top of your normal eating. I split it into 4 quarts and drank it between meals and in 27 days I gained 12 pounds half of which is shows up as lean body mass. It was "fun" but I am not sure what I think about the results. Since Thanksgiving is now past I plan to shed the fat I gained plus some. Cowtown 10k is 2-23-12 (about 12 weeks away) and I plan to shed 12-15 pounds while maintaining my Lean body mass (151-152 pounds). That will put me back in the 160s and 12% BF range that I was in back in May/June. 
I no longer fear gaining weight and I am now committed to a full body "powerlifting" program that I will build strength on instead of hitting a weight plateau due to switching my routine every 4-6 weeks. Never says never but now I have no plans to continue doing any endurance training and will still do HIIT cardio and running 5k and 10k races on occasion. 
Please feel free to tell me anything or share any opinion you have. It will not hurt my feelings and I like constructive criticism.
