Shannon, I can only admire your force of will! It should be really tough to be a good mother and to find a time forr yourself... And going after a hard day on a workout is always a victory!
As for St.Patty run - sounds nice, sadly, here in Moscow we have no running on that day (at least, it is not well-known) :-(
I have finished w2d2 and w2d3 as well. It was tough to go out at 6am, but I liked workouts, my feeling afterwards and the look of the city that is waking up. At least, today I reassured myself that all the people were looking at me - LOL, I found that they were just passing by on their way to work :-)
As for arms - I do not feel nothing wrong with them, but I really have neck and shoulder stiffnes that passes half an hour after the run. Thanks for your advice, Azatol, I used to push my hands across the chest, maybe that is the cause...
