In my current game I have 5 runners. One is a child. Yesterday I thought I'd try an experiment where I bred 2 runners. Also, the lady runner was a twin. I got triplets and I thought I was a genius. This would be something if the running attribute could be brought through genetically.

Alas, to my surprise, when the triplets were born, they all liked resting.

Very funny. Back to the drawing board.
