Hey Ed -
1. Make up your Goofy training schedule and have it start NOW. Every single maintenance run that you do from now until the "official" start of training is going to make the long runs easier, the recovery quicker, and the entire weekend of Goofy more fun.
2. Everytime you are tempted to blow off one of those maintenance runs remind yourself of how you felt at mile 23 of the marathon (or whereever it hurt most) remind yourself that THIS itty bitty run is going to make a huge difference in how you feel when mile 23 is mile 36.
3. Post this new training plan somewhere where you have to look at it everyday. My mom laughs because Dh and I post our monthly exercise schedules on the bathroom door. There it is staring at me first thing in the morning and right before bed. I hate going to bed knowing I blew off a run and some days thats the only thing that gets me out the door. On particularly bad weeks, my dh will write in some little words of encouragement (my favorite was "finish this run and we'll go to Outback")
4. Find a training buddy. I have two. I can't tell you how many runs that I would never had done if someone wasn't out there waiting on me to show up. Or how many runs I would have cut short if I was by myself.
5. Put new songs on your ipod. Don't allow yourself to listen to "running" music if you aren't running. For especially lonely long runs, I will download a podcast or two to mix things up.
6. Change it up. Drive somewhere new to run especially in the spring when the flowers are blooming.
7. Commit to yourself. Whether its a certain number of runs a week, or a certain mileage, or whatever. Tell yourself that you are going to do it - not because you are training your body - but because you are training your mind and your attitude.
8. Don't underestimate the power of a short run. After my first marathon, I tended not to "bother" with any run less than 5 miles. I figured I didn't need them. THen after a few months, I found that running was hard and I wasn't enjoying it. Stupid me, I was trying to run my longer runs without the maintenance runs to support them. I scheduled in a couple 2 mile runs each week and started feeling better almost immediately.
Its all in the attitude. you can do this!
