Just take any beverage with high sugar content. HFCS, glucose and fructose. Usually is HFCS 55, 55% fructose and 45% glucose
If need caffeine, take Red Bull.
Energey gels, some are fructose 2 and glucose is 1 (2:1), if it is formulated that way. Some do 1 fructose : 0.8 glucose .
I recommended to sales69 the Kang shi fu drinks. Choose the flavour and carb concentration. The > 9 g / 100ml can get pretty sweet. But all are nice flavours.
Only issue is possible sloshing for running, but not an issue for cycling.
Plan your running route so that it can loop to the nutrition point and you take it according to plan.
If i take gels for all the sessions, pok gai liao.
But some well to do cyclists i see take gels like maciam free one, each ride session can spend like 20 bucks for gels no issue. I think maybe the thinking is that already spent like 15-30k on the bike and apparels and stuff, this is no issue. (or for cycling holidays, that one also super blackhole).
