What products pack the most calories to use in half-IM or IM distance?

I have been reading about nutrition during long distance events (half-IM or IM) or long rides for that matter. What are the some of the best options (both liquid or solid) to ingest the “required” amount of calories per hour during the event?

a can of ensure/hour would put you over 400/hour

Carbo-Pro added to your favorite sports drink. Customizable to suit your needs. I’ve made 1K calories plus bottles. Important note: Make sure you you consume adequate amount of water with your drink.

Extran.

One 6.75 fl oz. box is 320 calories.

maltodextrins. just pack as much as you want.
carbo pro is one as someone said
hammer nutrition also has one

supposed to have no taste, but it has a slight taste, not really nice, so add one scoop of something you like, say cytomax something and you can have a 1000kcal bottle if you want.

“a can of ensure/hour would put you over 400/hour”

problems to consider:

  1. almost no one can ABSORB 400kcal/hr, so why take in an amount you can’t absorb?
  2. i believe ensure has a lot of fat (no?) and i’m wondering about the ability to absorb what’s not easily absorbable.

afaik, the most easily passed across the stomach wall, with no bad insulin oversecretion consequences, are a mix of simple and long-chain sugars, such as in fluid replacement drinks.

anybody have any different/better/newer info?

now, then, there’s the problem of hunger satiety during exercise—a problem fat solves—and however anybody wants to respond to that, be my guest.

FWIW, I think there were a couple of studies that showed that the theoretical limit of 1g carb/ kg body weight / hour was actually not correct as some things were messed up in the experiment.

Nearly all the fast IM guys are above 100g carb/hr inc. smaller guys. I think the germans are near 150g/hr (600kcal), some danes are at 200g.

I’ll ask Olaf (600kcal an hr in an IM) the ref. on the studies showing the problem with the initial theoretical limit

I’m not sure I want to know what’s in it, though.
