Hi Tom, You are not along in losing a spouse. Too many good people left us too early.
I am a slight female who began running April 2013. Have done a few 5k, then snow covered my sidewalk, have not run for 2 months. BUT am going to Calif Feb 17. Will run 4 times and come back to a 5K in March. I trained with Fleet Feet sports last year. Probably will this year again, I recommend them highly. That is in Cincinnati.
Tom enjoy your getting back into shape. You Can Do This. Phyllis :-)
