The good doctor has an APP that helps with this.

Soya sauce and maple syrup....it actually tastes great. Then hydration based on demand. Those little sushi packets of soya have 400mg of sodium.

I definitely use more solid foods when it gets colder because I don't need or want to drink as much. Just remember though that you probably need a drink a little more than you might think you do. You're still sweating, you're losing water through exhaling, and you need water to metabolize those carbs.

You can make a concentrate for one bottle. Easily done one the stovetop barely takes any mixing.

I like to do one concentrated bottle of my total carbs/calories and sodium needs (less sodium than hot days). Then I have extra water bottles to supplement my thirst. Thirst may be much different than in the summer so that gives me flexibility. I don't change the plan very much.

Thanks for the suggestions.

Shot of vodka in each bottle so they don't freeze. Three shots for a CamelBak...

The higher you push the concentration, the more you risk GI distress.
I can easily do ~400kcal / hour when I'm consuming 750ml+ per hour, but its hit or miss when I'm consuming 500ml or less per hour.
This is a place where Maurten gels seem to help supplement a less concentrated solution.
