I just started hitting the mountain bike again after taking the winter off. I agree completely that the season is more enjoyable when I am in shape and not limited by my physical conditioning. I find this to be especailly true the older I get

. One thing I notice is that even when I make it to eastern oregon in good shape, I still find it takes a couple days to acclimate to the difference in elevation and oxygen levels. Anyone else notice this? Or have any advice for dealing with the elevation change?
