I did a 2-mile run/walk with my dog today. She's building up mileage on the run/walks. My usual plan is for the run/walk to be an "easy run" but the dog wants to go, go, GO! So the "run" sections end up being more like speedwork. We did walk the last 1/4 mile because she was worn out. It was warm today - in the 70's. I think that took it out of her since it hadn't been that warm yet this year. I haven't been building up the long runs on the weekends like I'd planned to, but I might end up with a new PR in the 2-mile thanks to the dog!
