I'm still tweaking my nutrition for longs rides and tried something different at the Flyer. I have been experimenting on my shorter rides with this and it had been working, so with full support over 100 miles, I decided it would be a good place to experiment.
After talking to several nutritionists and endurance racers, I started wondering if I was still taking in too much plain water. My theory is that even though I am taking in enough calories/electrolytes, the additional water I was drinking was diluting the nutrition. So, why not include electrolytes in my water intake, and eliminate plain water.
The one element missing on Sunday was heat. It was humid but not hot.
The result of my experiment turned out well and I actually felt better than in the past. I also noticed that I was sweating almost the entire time and don't remember getting nauseous. Of course, I was on the single speed so it was more difficult to get my heart rate up and over exert.
I used nuun in one bottle and a personal sports drink mix with a maltodextrin base in the other.
Lots of factors, but definitely a move in the right direction.
