I have been thinking about that question a lot and to be honest, there is something I would change. I would have run more marathons, more often! When I was a new runner I thought I needed to wait at least 6 months in between marathons. So not the case! The first time I ran back to back races (2 weeks apart) I PR'd on that 2nd race. At that point I was hooked! Train once for several races...that is my motto... It is also good time management. It works for me. And YES, I am careful! I take rest days, in fact, at my peak I would only run 4 days a week. I do listen to my body, probably to a fault!
Running is my thing. It is what I do. But running has become quite a luxury for me lately. I
Since July, when I was diagnosed with degenerative joint disease (DJD), I have been so lucky to be able to run 4 marathons and 1 half marathon. And hopefully, will be running two more marathons this year. I have had to be extremely careful with my training. I don't want to make things worse, but I also can't sit back and let my knee get me down! You have to stretch the limits in order to find where they actually are. And that is exactly what I am doing. I know I will eventually have to take some time off to have surgery, but right now I am going to do anything and everything my body will allow me to do. And that makes me happy!
