found sodium citrate on amazon, https://www.amazon.com/gp/product/B00IOZIER4/ref=ppx_yo_dt_b_asin_title_o01__o00_s00?ie=UTF8&psc=1
I like the idea of copyying scratche’s formula as a baseline. i’ll look that up later.
Going to try doing mostly sodium citrate with some table salt for the chloride, since its a 24 hour race, it seems like a long time to be depleting chloride without any replenishment. Gonna have to figure out the other electrolytes, but might just rely on real food, bananas oranges that are electrolyte dense.
Since you sweat out mostly sodium, i’ve also heard you rely mostly on having good nutrition and stores of those electrolytes in the days/weeks prior to your race, as opposed to replenishing the day of. So i might not have to worry about getting tons of the other electrolytes if my nutrition is on point.
Also got some maltodextrin and fructose powder for a supposedly optimal carbohydrate mix.
Maltodextrin - 5 lb Bag
I’m going to mix it all up and start using it on the trainer, and then see if my stomach handles it when i start doing longer rides when the race gets closer.
