I wussed out and did my 4 mile run inside rather then braving the pouring rain and wind.. Right away I did not really feel good - it felt like I had a brick in my stomach. I'm not sure why and it never went away. But I did finish my 4 miles and a 10 min hill in 36 min - 9 min mile pace the whole time. My legs are a little tight, and so are my lats - but no big deal I streched out after I finsihed my run. Other than my stomach it was a very uneventful run.
