I just tried week 6 run 3. I struggled the whole time but I was pretty confident that I would finish, but with 3-4 minutes to go I got a horrible stitch in my side -- probably the worst I've ever had. I tried to keep going but I was practically doubled over, so I had to stop. It's the first run I have ever failed to complete; I've repeated a lot of runs before, when I didn't feel ready to move on, but until now I've never been unable to finish a run.
I know what everybody says, that we all have bad runs and that I have made great progress from where I was in the beginning. But it still feels like I'm not doing very well. I have never been able to get into a rhythm and zone out while I run, and I'm painfully aware of every breath I take, no matter how slowly I run. I thought it would get easier, but I still dread the days that I have to run. I'm not going to give up, but I feel like I'm never going to become a real runner.
