Unexplained Behaviour

I was weeding the area which had been cleared away at the front of the house, and while there I happened to notice Chloe in the pasture acting a little unusual.  Since I often am not watching the horses for long stretches of time, perhaps this behavior wasn't so unusual and she does this little exercise jaunt daily.  But it definitely was the first time I've ever seen her behave this way or any horse actually.
