I don't see this as failure.....starting this week, I switched to the most basic marathon training plans I could get my hands on....Not only that, I am also loosely going to follow it only for the long runs and just make sure I get in 4 miles three times a week plus weight-training once or twice a week.
During the summer I was able to complete up to 8 miles on a weekday and not have it dent me. But now that school starts back up and I have to teach I would need to get up at minimum 4:20am, and that is just when I run 4 miles. Partly it's the fact that I am a slow runner but I cannot change that much at the moment. If I were to complete an 8-miler during a workweek I'd have to get up at 3:20am!! That would not be easy to maintain and keep my sanity and health. Last week, I did an 8-miler and was trying to do a 17-miler the next day and felt a painful pull in the back of my thigh. The LAST thing I want is to get injured. Then, I remembered that my 50-miler is 6 months away and that technically I am still just training for just marathon for the moment, and to top it off, I am just training for a marathon I want to finish and not win or even PR, at this moment.
* 4:20am: Wake up to get ready for the day
* 5:20am: If I were to run 4 miles I would need to leave the house
* 6:20am: Get home to shower and change
* 6:50am: Leave home
* 7:25am: Get to work
So, it's with great assuredness that I made this decision to lighten my load and I already feel a ton better.
