I've had a plan (since June) to run the AZ RNR marathon in January 2011. I have a free entry and have been training in a Runners World "break 4:30" plan. The plan calls for 4 runs per week including a long run on the weekend. The past three long runs have not been fun at all.
To make matters worse, I had 16 scheduled today and quit at the 10 mile mark. I had no mojo and no desire. The run itself wasn't horrible, just not fun; not enjoyable. So around mile 7, I started thinking about quitting and calling my wife to pick me up (this eventually happened), and I fought the shame and guilt for three more miles and then threw in the towel. Fuck.
