Carb storage for unsupported ultra races

Bruuutal. Fat oxidation ability is useful for you for sure if that’s a feasible situation (clearly is!).

Dr. Harrison, I can see the logic in the above statement. I have a question, though: before learning from the podcast of the 1:.8 ratio for Malto:fructose (or 2:1 glucose:fructose), I bought a BUNCH of HEED from Hammer. HEED contains only malto, according to my review of its ingredients. And now I am curious whether it would make sense to buy some fructose and combine it with the HEED I already have, in that ratio. I am trying to a 90g carb mix put together using the HEED I have purchased in bulk, and this thought occurred to me when reading your post.

Great question. I’d personally just do it using sucrose because I’m cheap.

That’s sort of the structure around which I initially started writing the app I’ve got in beta testing now. It prescribes fuel, and then takes care of the sugar + whatever math. Heed is one of the listed products. I’d just put a scoop of Heed in a bottle and do the rest of what’s recommended by the app as sugar. If not using any calculations or app, just throw in “mostly sugar, with a scoop of heed” and your ratios will be great, and it’ll taste nicely mild too.

But, yes, could use fructose alongside the HEED too. Eventually the app will have an option for selecting fructose, and the app optimizing whatever fuel products are used to a 1:0.8 ratio, but for now, it’s just sugar and I just let it do the servings math and overall prescription for me.

Sounds like a very neat app! Thank you.

I do have a food scale so I will probably start with 40g HEED: 32g Fructose (72g / 500ml bottle), and then work from there. Going to try that during my workout tomorrow.

Thanks and good luck developing the app!

Most of my bibs have mesh pockets, and I can carry a lot of bags of powder & real food on my legs. More than enough room for 8 hour events.
