Yeah, I just literally use table sugar, which is 1:1 glucose:fructose. Maurten et al using 1:0.8, close enough! And I don't believe the hydrogel thing is any magic, just marketing.

But yeah, this is a thing. There is some gut distress for sure at higher levels of intake. See guy finishing second -- still under 2 hrs! immediately puking, which is fairly common at the high intakes. I've heard of Blumenfeld (the triathlete) taking like 200g/hr or more. Insane. Though he's had some epic GI disasters too, lol.

The hydrogel textures (not maurten but naak, but close enough), for me, allow while racing to swallow a full 40g gel in half a second without feeling the sugary taste a lot, which is nice. Compared to thick syrup-like gels, it’s a way better experience in a marathon.

But I only buy for actual races, rest of the time, I do my own 1:0.8 mix with a bit of thickener, in soft flasks. Much more cost effective.
