I will make sure to do that - I'll have to figure it all out when i get the malto and weigh it all out and subtract the existing amount of sodium naturally occurring in the apple juice. Any guidelines for sodium intake per hour in mg for racing in hot weather for 160# rider?

I notice HEED is very very low = 40mg per 100 kcal
GU is 240 mg per 100 kcal.

Huge difference there...
I don't know if I should be looking at this in terms of sodium intake per hour or sodium intake as a ratio of water or what...
