I cleaned the bike properly before a long ride sunday and couldn't see any other areas that would cause a creak. It's definitely coming from the crank area and is the same noise as before. Can't think what else it would be. Pedals are tight, no movement in the cranks from left to right (so not loose), no frame cracks that I can see....
I assume you checked the bottom bracket. How about the cleats on your shoes. Those can creak as well when they wear out.
