Well, my last Week 3 run was on Thursday after work. I didn't run home from work, I walked home from work (2 miles) and then went for my run. I think it may have been a bit much, but I didn't think about the run as much as I had before. Does this mean it's getting easier? It seemed that way. I wasn't as out of breath, but it all felt a bit slap-dash so I'm going to focus more tomorrow on warming up properly and not rushing things.
