As Johno59, said, make sure to put brakes on it. At least a front brake. I ride fixed pretty often and trust me, you'll need a front brake. Some don't use a rear brake on fixed gear bikes, but I always have. Yes, you can slow down by adding back pressure, but a brake still helps.
I do like to ride and see if I can complete my trip without using brakes at all. Many times I've been successful in doing just that. But I would never be without them.
