For me that's situation normal. When I put in big/hard days on the bike I don't have much volume the follow day. When I ran marathons and ultra marathons, that would last for up to three days. I always attributed it to less blood being in the intestines because of demand elsewhere during training or the event. I have absolutely no idea is that's true, but it's happened often enough that I don't worry about it or try to find the true cause.
