The amount of events that will require careful fuel training is pretty limited to long distance time trialling though isn't it. If you're doing multi-day ultra cycling you'll be eating anything you can find. If you're domestic racing a few gels for anything with any distance. Smashing gels on your turbo just because you're doing a tough turbo session is a great way to rot your teeth.
Not at all. Sprinters are doing very short events but have to compete in heats over a day or days. Knowing what works before and after races is critical!
Road racers enter events understanding they might not finish with their teeth anyway so that points somewhat moot.
