I think i will end up about 8 hours short. I upped mine 3 times, but I was not really sure I'd make 150. When I look at my numbers, I did much less in December than the other months, which truly is a function of it being the tail end of the cycling season (usually ride less than 5 times) and no snow for nordic skiing. So, going to the gym is usually not more than an hour, while outdoor activities, at least on the weekend are usually 2-3 hours. I did hike a bit in December, but I was still trying to baby my foot. I've had more injuries this year, than in the past!
