Week 4, Days 2 and 3

On day 2 I took my walk along The Embarcadero. Yesterday (Day 3) I attempted to run, but my legs felt heavy, my mouth was incredibly dry, and I felt really tired. After 10 minutes I finally stopped running and instead used the elliptical machine for 40 minutes. So tonight, even though I'm supposed to walk, I'm going to run to make up my missed run of yesterday. Hopefully I just had a bad day.
