Reddit mentions of Gatorade Powdered Drink Mix, Frost Glacier Freeze, 76.5 oz., Makes 9 Gallons

Peanut Butter is a big one, there is nothing that will make you feel more at home. I was never a big peanut butter eater, but after 6 months I was craving it.

I made sure to bring Sriracha and peanut butter in my bag. I had a lot of stuff (seasoning salt, ranch dressing mix, curry pastes, and good coffee) sent in a care package. PST is a crazy time - I never once thought about pulling out the food I brought, I just ate whatever was put in front of me. But it's nice to share some American snacks with your host family.

Edit: Gatorade packets are also great. I was able to get them from the PC office, but something like this would have been awesome.

If you want liquid carbs and sugars, there's existing options:

The advantages of gels and standalone carbs is:

• More total water stored on the bike because the bottles volume isn't being taken up by 3 scoops of powder
  
  
• Easier to shift the ratio of water to carbs as the ambient temp changes. Maybe the clouds disappear and now its hotter and you want more water per unit of carbs, if everything is pre-mixed, you don't get that adaptability.
  
  
• Refills are not as simple because you have to have a way to carry extra powder, then pour in the powder without spilling it, then put in the water.
  
  That said, it's not black and white. Liquid carbs might work better for you, I recommend trying it out.

I know some serious long course triathletes might scoff at Gatorade, but man, I love that stuff. Tastes good, mixes well, you can mix it to your specifications, and it's so cheap it's almost free. As an Oly distance racer, I feel like Gatorade is "good enough" for nearly all my training, and I just need to try out my race nutrition a couple times before the actual race to make sure it sits well.

I get sick of doing it too, I do two weeks worth at a time with individual dosing into these little red silo cups I have. I'd like to bulk mix as well but have the same concerns as you about distribution in the mix. For flavoring I add a 2g scoop of Gatorade powder to my mix, I got this big old thing of it.
