So last night Chelsie, Ryan, and myself went for a walk/run (we walked most of the way since we are not at all runners but then towards the end we tried alternating between walking and running). We went 4 miles in an hour which I know is pretty slow but at least for me and how out of shape I am it felt really good. The only thing is today my back is killing me! Not sure if it's just cause I am not a runner or maybe my shoes? Hope some ibuprofen helps!
