So many factors here, but you can get as fancy or as simple with your pre/intra workout nutrition as you'd like. I usually workout first thing in the morning, and will always have water, caffeine, and electrolytes, and then depending on the intensity of the workout will have carbs. Sometimes that comes in the form of honey in my coffee or just straight off the spoon. Other times, for longer runs or if going from a run straight into a lift, I might have straight table sugar and table salt mixed with water in a shaker bottle (can use some sort of mio or cyrstal light packet for flavor, but it's pretty fantastic on its own). Electrolytes is usually 1/4 of iodized salt under the tongue chased by some water, or the fire department I work for is sponsored by LMNT, so I'll have one of those if I'm on shift.
As I mentioned, you can go as fancy (expensive) or as simple as you'd like. G1M Sport by BPN is a great pre/intra carb source, LMNT are a delicious hydration solution, and pre-workouts/energy drinks can be fun to try. But sugar, salt, bananas, honey, coffee, etc can and will get the job done as well. All comes down to personal preference, budget, training demand, and whatever nutritional dogma one adheres to.
