I've never been terribly inclined to do group runs. I do enjoy the atmosphere and camaraderie of races. But, when I am grinding out the miles in training, I have always preferred to run alone.
Admittedly, the group run I went on today was not exactly typical. But, it sure was fun. For the first time, I ran with my grandson (well, OK; he was in a stroller). And the dogs came along too just to make the comic scene complete.
I only made it three miles--running with a stroller is not as easy as it looks (even a not-so-cheap stroller that is sort-of-designed for running). But, hey; they were three quite glorious miles punctuated with giggles, laughs, and a good deal of nonsense. What more could you ask for?
