"somewhere between 60-120g carbs/hour" and that's on the flat stages (more in the mountains) of TdF would be considered junk food anywhere outside of sport.
Elite endurance athletes have awful diets by any normal standard, because the only way to fuel yourself adequately for a stage of the Tour de France or an ultramarathon is with nauseating amounts of refined carbohydrates. It's not even the fun kind of junk, just a constant effort to eat as much carbohydrate as your gut can possibly tolerate.
I don’t know if any athlete who can sustain themselves on a junk diet.
