Looks like my greatest physical liability has stopped me again. Yes, my lower back is acting up, probably thanks to yesterday's run. I walked/ran two miles yesterday. My goal is to run the entire thing before I head home at the end of next week.
This brings up an interesting question: which is more important right now, a general fitness challenge or my running. As I've already signed up for my second 10k in May and really want to run the entire thing, I have to say it's my running. As such, I need my non-running days to let my lower back rest and recover so I can improve the next running day.
I don't like giving up the challenge, especially as I made it half way through with no major issues. However, I uhave to have my priorities straight. Right now, running is a much higher priority.
