I’d eat far more before a ride, particularly if I felt it was likely that I@d be hungry.
That said, bear in mind that cramp will happen sometimes, particularly if it’s a ride that stretches you a bit.
If I had the time/inclination to do it properly, I’d probably have something along the lines of:
Large bowl of porrdige (probably minimise simple carbs i.e. syrup) or muesli.
Couple of big thick slabs of toast with some eggs and maybe tomato on.
Usually the toast just gets marmalade on.
I don’t really “believe in” energy gels (or for that matter the need for electrolytes), but if they fit in your pockets and you like them then go for it.
