Ok, I am trying to fine tune, actually increase, fluid absorption. I have a very high sweat rate of 70-80oz per hour, under current climate while running. I have read of recommended sodium/water ratios of 700-1400mg/liter (32oz). I would assume high seat ratio = need high sodium ratio (without getting a lab test on sodium concentration of sweat). I believe this the generally the case(?) In terms of emptying the gut of all this water I have to drinK, is it correct to assume higher sodium = higher absorption rate?
So far I have been able to drink about 60-70 oz water along with 1100-1300 mg sodium (Thermolytes + gels), felt a little full but it was manageable…but I would like to increase fluid intake ideally to 80oz or so per hr (feel sick just to think about it…but not much of a choice). So I would appreciate feedback or experiences to try shorten the trial and error period during long runs/rides.
