well, first run was treadmill and it was ok, not too difficult. quads felt a little tight but that was it. Today i ran outside and i have to say my chest was very tight. don't know if that's normal for a second run or due to it being a bit cold. Either way i managed and felt pretty good at the end. I am NOT interested in distance, I am purely listening to Laura and trying to feel comfortable in the running phases prior to week 2.
