The "Challenge of Champions" series of adventures has the advantage of being based on "Project X," an obstacle course sort of set-up used during the USAF's Squadron Officers School and during the field training they send their officers-in-training through. (I got to go through one version during AFROTC after my sophomore year in college and another version during SOS as a Captain.)Dungeon Magazine has a few 'Challenge of the Champions' series that had traps and puzzles you can pirate for your needs.
