Thank you to all of you for the kind words and congratulations!
As Cath mentioned, this hike has been almost 2 years in the planning for us. After having to put it off on more than one occasion due to time constraints and injuries, we were both thrilled to have the opportunity to give it a shot. Completing the traverse (and within our time goal at that) will always stand out as one of my best memories of 2011.
The topic of mileage and elevation gain has already been covered, but I'm happy to share some details on my attire and nutrition/hydration strategy for endurance events.
Footwear
My shoe of choice was the Brooks Cascadia 6 paired with Darn Tough socks.
The Cascadia 6 is an incredible running shoe, especially for folks like me with ankle issues - comfortable, stable, breathable, and extremely durable (I've got over 500 miles on my first pair and they are still going strong). From Pemi Loops to 100 mile races and everything in between, the shoes have never failed me. The only downside to them is the rubber compound on the outsole. I tend to favor a "stickier" rubber that grips well to wet rock, and unfortunately the Cascadias are not great in that regard. Nevertheless, I'm willing to live with that given all of their other amazing features.
I've been a die-hard Darn Tough fan since I started hiking. I find that wool socks really keep my feet happy and blister-free, much more so than the Drymax socks that a lot of folks seem to be wearing (though I do like them, too).
One other odd thing that I do - but that I swear keeps my feet from blistering - is spray up my toes, ankle and heel with liquid bandage product (such as New Skin). It's a bit of a peculiar strategy I guess... but I'll take anything that makes it possible for me to go an entire 55 miles without changing shoes or socks once!

Nutrition/Hydration
I try to consume around 200-300 calories/hour to maintain a steady energy flow. When doing an all-day hike, my fuel is usually in the form of gel and bars. I'm a big Honey Stinger fan (both bars and gels), and also really like GU Chomps when I'm in need of an immediate boost. Additionally, I try to eat a real meal at some point in the middle of the trip (we stashed a cooler at the Highland Center with burritos, wraps, and other resupplies).
Two supplements/food sources that people tend to overlook on longer hikes are salt tabs and protein. When it's humid and hot out, I take 1-2 salt tabs/hour to prevent dehydration and cramping. For distances of 50 miles or more, I also find it very helpful to consume an endurance fuel with protein and amino acids - such as Hammer Perpetuem or Succeed Clip 2. Endurance fuels are not cheap, but I've had great results using them in all of my ultramarathons. I find that they keep my stomach happy, provide consistent energy, and also (perhaps most importantly) assist greatly with my recovery after the event. For the H2H, I'd switch between Perpetuem and NUUN (calorie free electrolyte drink) each time I refilled my water bladder.
Please note that these are all strategies and products that have worked well for me. I'm certainly no guru when it comes to endurance fueling and supplementation, but if you're interested in exploring the subject more there are some great articles
