1800 miles in 3 months

I went back and charted my miles since the first week of June and give or take a few miles I'm at 1800 for the 3 month period, averaging about 150 a week, although there are two weeks in there, in Iowa and Italy, where I did close to 500 miles each week. So more than half of my miles during the 12 week period were done in two of those weeks alone. I may be off on my math somewhere!
