Can't upvote this enough. Carbs are king for endurance, though I tend to drink most of mine as I find it easier.

I find more liquid gels are nice and palatable during runs. SIS ones are nice in that respect

For gels, I do maple syrup, which usually comes with a pinch of salt. I will also add 50-100g+ carbs per 750mL bottle. I find it hard to chew solids when biking at anything higher than low Z2, it actually increases my heart rate a bit.
