My friend Bart and I drove over to ride part of the Natchez (Mississippi) Trace Parkway on this fine Memorial Day and all started well. I'm no hill-climber (living as I do in flat Louisiana) and while the Trace is not moutainous there are some mile-long+ hills that wear me down, but I was doing OK all things considered. When we reached a turn in our route I decided we should take the longer direction and end up with a metric instead of a 50 miler. Bart's done metrics and centuries, so he's OK with it.
We took periodic stops, but on our return leg I finally had to stop at about mile 50 and walk around to try and convince my legs to keep on responding. I was also seriously out of breath. By that time, I had eaten two bannanas, a sweet-n-salty peanut bar (with sugar in it) and drank about 3/4 of my two GatorAide bottles. After a few minutes it all came to a head and I ... liberated ... my stomach contents in a most enthusiastic and repetitive manner right there on the right-of-way.
After a little while longer, I generally felt better, so I nibbled a Zone bar Bart gave me and sipped the remainder of my GatorAide. But I was in no shape to continue, so Bart generously rode to the finish line and brought my wife's minivan back to me.
Wondering why I bonked so 'easily', we later realized that according to my phone app (probably not exact but in the area) I burned 3000 calories but the GatorAide I was drinking was "lo fat". According to the label it has "5g,13g' (?) of sugar (20 oz). I don't have any "hi fat" GatorAide on hand to compare, but the bottle of PowerAide I bought on the way home had 34g of sugar in 24 ounces, IIRC. Quite a difference.
Moral of the story? Next time I try a long ride I'll carry a birthday cake or bag of powered donuts with me. I've learned my lesson.
