Yeah and just plain shot - out of gas. Great place to park your bike, looks like a nice setup.
Hard to say for sure, but you might recover more gracefully by having a glass of milk after riding or something a little more substantial to eat during your rides.
Congrats on the ride. I agree you probably could use different food on the trip. Maybe PBJ sandwich or Clif bars. Be sure to eat a good meal within an hour or so after a long ride.
Congrats on your ride!
Couple minor comments - do you really need 2 panniers for that ride? All you needed to carry was a couple bananas, maybe the gatorade. If you can't manage with your pockets, at least reduce to one pannier, I swear it doesn't feel lopsided/unbalanced, I do this on my tour bike all the time. Less weight = better.
Try replacing the Gatorade with another sports drink, Heed or Cytomax are what works for me. The digestive issues might be from the Gatorade.
Oh and +1 ditch the panniers, it's not really the weight i find but the aerodynamic drag. Trunk bag?
