Didn't feel so great. The last time I was tired and kept running, I was reeeeeally tired the next day, so I stopped and walked back. Sigh. I think it's time for my season break. Even if my volume wasn't high for the entire season, my effort was, so it's pretty reasonable to rest. For me, a season break usually means jogging 30 minutes every other day, but because I'm *actually* a bit run down, I'll do what I did in high school and take it almost completely off.
This is probably not the cause, but the inexplicable tiredness reminds me that it might be a good idea to check up on my iron. I think my doctor's office does appointments starting at 6:30 am, so that would be convenient.
