What an hour on each looks like — and the two together
Specs tell you what is in a serving. This tells you how many servings an hour hit your target, what that delivers, what the race costs, and what you would carry. Set your own target from the finder and it follows you here.
None of these is a carb source. Electrolytes and salt caps carry a gram or two of sugar at most. Add a gel, chew, drink mix or bar to build the hour.
Sodium and caffeine show what these products deliver at that rate. Your caffeine dose comes from the caffeine tool, and the drink-mix tool checks a bottle's concentration.
