I completed week4 day 3 yesterday!!! I am so proud of myself! I am not and never ever was a runner. Well, to be honest, I am not running. It's like a leisurely jog at this point but hope to increase it with time. Not sure what will happen from here on out but I am feeling great and plan to take it day by day. The thought of running the entire time seems very unlikely but I am going to give it all I have. I am 43 and overweight so it is just time to get this under control! Good luck to everyone! I am so inspired by reading posts by others, motivates me to keep truckin'!
