B. really wants to run a 1/2 marathon in March '08. I really want to do it with him. However, I've trained for one before and only got up to 8 miles before deciding that I was crazy! I just don't know if I can push my body 3 more miles! I think it would be such a cool thing to do and would be something fun for us to do as husband and wife-o. Any tips out there in blog land?
