Heh. I actually don't even remember walking down the steps. They'd run out of space blankets and I was going into hypothermia ... even with the wool jacket my husband had brought me, my teeth were chattering by the time we got back to our hotel. No ice bath for my legs!
Years ago I sometimes ran the stairs at a dam, but only uphill - half a mile down the embankment and back around to the bottom. Brutal is right. A friend of mine used to say, "102 steps and every one has a name." 
Thanks for all the good wishes folks.
Now back to my regularly scheduled life (until it's time to start training for the next one).
