I have downloaded the RP Endurance guide @Dr_Alex_Harrison and read the many threads on custom drink mixes. I’m hoping someone can check my mixes to make sure my calculations are right. I am planning a 150 mile ride up the California coast and I have been training with different drink mixes. My FTP is about 276 and I weigh 205. Based on everything I read this mix seemed to be what I should use. Or close.
I wasn’t sure if a ¼ teaspoon of Sodium citrate was 250 of sodium it was hard to find that calculation.
This mix seemed to work well with no stomach distress using a 23 ounce bottle and a occasional chase with water. I use the Specialized insulated purist bottles because I like my drinks cold as long as possible. I have done anywhere from 1 to 6 hours with a bottle an hour, no problems. Lately as the heat picks up to the 90-95 range after two hours I am very thirsty. I am assuming it’s just not enough water? I usually carry 5 water bottles with me because I like to keep riding. 3 bottles are drink mix and 2 bottles of water. I am assuming with the increase in heat I should be drinking at least a carb bottle and half a water bottle an hour? About 35 ounces of water an hour? That means more water stops I guess? I wasn’t sure if the amount of sodium played a role in how thirsty I am.
I also tried this mix because I have used this custom blend for about 3 years without any stomach
problems, then I started reading that I may not be getting in enough carbs so I modified it, but Infinit
says it is no longer isotonic which I read may not be as important as people once believed.
Any suggestions on modifying these two mixes to make them better for me. I am assuming the Infinit
mix is a 2:1 as that was the popular thinking at the time. Thanks for all your insight. I have one more ride
on Saturday to dial in a mix and then I have to put together about 10 baggies of mix to carry with me on
