Back home in savannah he'd take a walk every morning that he could. It didn't do to be a town doctor and not be fit. Then the Academy had their goddamn hellish fitness regime to stick to and when on a ship? Well. Sometimes jogg'n was the one thing that made the Enterprise feel a little like home. The apartment got so damn quiet when everyone was out- before he got lost? It didn't bother him.

Now? Now he chugged along, hanging back with Greg to offer encouragement- it's not easy on him, he can see that. but he's doing it anyway, working hard and that? That's more effort than he'd ever seen in half the idjits he had to work with in Georgia. "Hold up Wash."

Bones slows to a stop alongside Greg- he'd been adamant about giving the man a chance to drink, walk, or just breathe. FItness is well and good but not when the chase kills a man.
