Shadow Walk. I'll need some rest periodically to recharge spells, but... well, undead divine caster - that's a 60 minute prayer break. I can bring the whole party at 50 mph for 23 hours a day, provided everyone else can keep up with the forced march. And a few Mass Cure Light Wounds takes care of the nonlethal from failed checks.
I can also have us use "road or trail" for overland movement if that helps. I get a +5 on survival checks to avoid getting lost if no one else wants to try that bit.
Back on my normal work schedule. Updates will happen when I can finangle them at work or on my nights off on Monday and Friday (unless I get caught up doing something else).
