2 miles on treadmill

Been feeling really worn out lately. Wanted to do a long run on Saturday but was too tired. The 2 miles today was tough. Got new Brooks sneakers but they hurt my left ankle. Wanted to try a different brand because my right knee has been achy. Ran 2 and walked a bunch because I wanted to finish watching Marvelous Mrs. Maisel. Seriously the only thing getting me through treadmill running!
