stroller moms

There's a wooded park that I drive by each morning on my way to work, and if If drive by at the right time, I see a group of moms working out. I know that they are moms because they each have a stroller. Usually when I pass by they seem to be just warming up. They stretch their legs and arms; twisting, reaching, lifting, sometimes with one hand on the handle of their stroller for support, sometimes taking a step back. I only see them for a moment as I pass by, but they seem to be encouraging each other, glad that they have companions to help each other get or stay in shape.
I wonder what the babies or toddlers think about this. Do the babies look at each other, used to the routine but still not knowing what it's all about? Are they impatient for the stretching to be over, ready to be pushed along the gravel path?
I wonder if the moms have to go single file along the path. Today there was only three moms that I saw, but even so I don't know that the path is wide enough for them to stroll alongside each other. The Olympics are on right now, and when I think of mom's pushing strollers single-file down a path at a brisk pace, I think of speed skaters; all in a row, taking their time and setting a good pace for the first couple of laps before each begins to pick up speed and try to dart to the front of the line, weaving in and out of order with the rest of the competitors in an attempt to get to the front of the group and win. I don't know if the stroller moms ever race down the park path. They might. I'd like to see it if they did.
