I'm trying to decide what animal to get for a tattoo...?

I'm trying to design a tattoo for myself. I'm already using a pea feather as part of it, but I'm wanting to incorporate it with an animal that reflects me. I'm a runner, I love to run, the rush of it, the clarity - and I want to incorporate an animal that reflects that side of me, like a cheetah or something? Any suggestions for an animal that represents speed?
