If there's a writers equivalent of a marathon than doing the prep work for Dean and Kris' workshop might be a good candidate. I'm used to diddling around with a short story for a two or three weeks before I polish it and send it out. It sounds lazy but it's not. Since short stories aren't worth outlining I tend to approach them like a jigsaw puzzle. I know the overall picture and I spend a couple hours at a time staring at the pieces until I figure out where one goes. Then I'll go work on something else for a while until I feel like staring at the pieces again. However this time around I don't have the luxury.
It's frustrating and stressful as hell but at the same time it's good to be pushed like this. Spending that much time on a short is kind of ridiculous and being able to finish the puzzle faster will be a good skill to have. So if you'll excuse me, I'm going to go back to placing those pieces. I've done enough "impossible" tasks this year that I don't doubt that I can do it. I just need to sit down, focus, and prove myself right.
