My cycling drink mix:

2 pkg Kool-Aid (Tropical Punch is my preferred flavor)
1 1/8 cup granulated sugar
3/4 tsp table salt

I put these three ingredients in a secure container and shake very well and store. When needed, I put 3 tbsp of this mix in my 22 fl oz cycling bottle and pour cold water and shake well. This makes approximately 6 total bottles.
