Genuine Q – why do people use energy gels?
A mate who used to win 24-hour solo mtb races and do stupid FKT long-distance route things found they were the only thing his gut would tolerate on a sustained basis. I have vague memories of Rickie Cotter saying she did the same for similar reasons, it sounded less than glamorous.
I occasionally use one as a ‘break glass in case of emergency’ measure if I’ve screwed up fuelling on a big day ride.
Fwiw, read the ingredients lists some time, lots of artificial sweeteners, emulsifiers, preservatives etc, which may or may not bother you. SIS seems quite bad for this, Torq somewhat better. I get that people’s tolerance for such things is variable, particularly in performance mode, but if nothing else, a fair few artificial sweeteners list laxative qualities as side-effects, so smashing a load of them may not be that great an idea, ymmv.
