Shillelagh Four Mile Run and Walk

Mary and I signed up for a 4 mile walk up in Flushing, Michigan next Saturday. Up to this point the longest walk we have done has together been 3 miles (Mary has done triathlons). I have been walking on the treadmill a mile a day during the week. This week twice I have been able to do my walking outside which I greatly prefer. On those days I do a mile and a half. In spite of my walking, three weeks now, I am not losing much weight. My tummy sticks out so much I am considering buying maternity clothes!
