I did five miles today! Roughly 2 miles ran, 3 walked. I am really pleased with how I fared. I'm getting used to the physical exertion, and the lungs are keeping up now as well. However, toward the end I really felt like I was landing too hard on my heels. Something is not right with my form, which isn't surprising. So I am gonna research it, and try some different things, and see how I can improve it. I'm making sure to stretch realllllly well before and after, to make sure I minimize the chance of injury.
Anyway, time for some food and water and a good shower.
