OMG Joanna, I can hear my dad when reading your post. "Yous kids don't know how good yous have it. When I was a kid I had to walk 10 miles to school, uphill both ways, in the snow, with a broken leg. Only to find out that school was closed by the time I got there!" My reply??? "It's y'all dad, is yous even a word?" Haha
I can totally relate to the gain. The other day I weighed in at 192 point something. At one point I was as low as 168. Buuuutttttt it is what it is. As far as the 1/2 marathon, if I can do it, so can you! Where is the race?
