Tournament.

My players are asking for a four week mini campaign. So tasks/adventures utilising various skills and scenarios. To be clear its a competition mini campaign they want.

Any short or long lasting puzzles or ideas welcome. Thank-you in advance.

The Victory Point system is the basic framework for that type of thing. From there it is description and details that just need set up.

All PFS scenarios have skill challenges. You can pilfer them to your heart's content.

Which AP's have the best or at least most interesting skill challenges?

Sky King's Tomb uses all of the subsystems for skill challenges in the GM Guide throughout the first two books of the AP. I find a lot of them to be interesting, but YMMV depending on your table.
