Hi,
I have a few questions about using carb powder (e.g Isostar),
(a) what concentrations to people use, and what duration of run would u start to use it?
(b) if you use it for say, a 2 hr training run, I'm guessing you will actually get less fit, or certainly lose less weight as your drinking glucose?
(c) Has anyone tried the decathlon stuff, which is half the price of isostar?
(d)any other pointers about carb powder for runs in general would be appreciated. i'm just a little concerned about what to use it for, and if it will then have a detrimental effect on my fell running without it!
Many thanks
