That's the problem with just drinking Gatorade. I don't think it has enough nutrients to help prevent lean muscle tissue cannibalization and hasten recovery.
I was there this morning with a friend and did another 20mile (1 loop). 
Gatorade is only my "during the ride" drink (although usually I use CytoMax...was just too lazy to make it that morning!). When I got home, I did the whole whey-protein-drink thing, as well as generally fed myself well.
How'd the ride go this morning? I'm assuming you went harder than you did with me...

(I rode my trainer this morning for an easy hour just to warm things up and elevate my heart rate. Will hit the road/trail again on Friday...)
