If it's the little piggy that went to market, you're probably in for some discomfort. My wife did that one a few years ago, and it was a fairly big deal. She practically had to learn to walk again (it was a serious smash, not just a little crack).
I've broken both little piggies that cried wee wee, and after the swelling went down, it wasn't that big a deal. You may be able to tape the affected toe to the one next to it for support, which helps. My doctors didn't splint me or do anything like that either time, just told me to take it easy. I'm guessing at this, but based on my case, bike shoes might be stiff enough to support the foot so you could ride without much trouble if you don't go hard.
