Don't be too hard on yourselves, you did a lot in 2 days, and a lot of you have been training for this. If you were football players you'd all be in recovery week right now, where if you did workout it would be light and easy = no Cathe workout.
Give your bodies a break if you don't, you'll be at a higher risk of getting a summer cold. Then you'll be off another week, because you'll be sick. Also remember most of you flew into a different time zone, even for a couple days this screws you up, especally when 7 am, for you was 4 am. So your body is confused right now, and it needs rest and not you bouncing around.
Also when you wake up in the morning take your pulse and see what your morning resting heart rate is at and keep track of it for a few days, if it goes down a little. Your body really needed those days off, as that is a huge indicator of over training or too much at once. But also once it goes down, that's the okay sign to start again, if you over did it.
I'm glad to hear that everyone is listening to their bodies, remember to take it easy and listen to it. It will tell you when it's recovered, do some stretching and some light work, that will at least comfort your mind your doing something and it won't cost your body much if it's trying to recover.
