I have posted about how I've found it really difficult to run the past couple of weeks. Well, I went for what I thought would be a nice gentle 4 mile run tonight and felt like crap the whole way. I was feeling a bit breathless after 1.5 miles. I have never felt breathless from running, even when I'm doing 6.30 pace for a half marathon. I refused to give up and walk home, but it took me 30 minutes to complete 4 miserly miles and I was seriously sweating and knackered. I just don't understand what is wrong with my body. I don't feel ill or anything, although I haven't been sleeping that well. Anyway, i'm not running tomorrow, and just hope my long runs this weekend go a bit better.
