I also love to ride with my Collie Betsy, she's only a little lady and not quite as fast as that. Destroys me in the corners as she knows where to cut them!
I don't usually take her more than five or six miles total as longer distances could damage her joints and/or heart. Collies are bred for rounding up sheep so need shorter bursts of energy instead of long distance plods.
