This is just my two cents (if worth that!), and I'm sure others do things differently. For me, I use my training as practice for my actual races. I want to know how my body is going to react to what I do on race day (well, as much as possible!). So, if I am going to be drinking and/or fueling during a race, then I better practice drinking/fueling with the same stuff during my training runs.
I want as much control over everything as possible (ha ha!).I don't want to hope for the best when I get to the aid stations. I've heard horror stories of runners thinking they were getting water and it being "gatoride" (or equivalent), or vice versa. Or, the runners practice with the beverage advertised to be used in the race and the race volunteers mix it at a different concentration than what they practiced with and that leads to tummy upsets. Or getting to an aid station expecting to be able to get some fuel and they're all out!
At the marathon I ran in December, hard plastic cups were used. I saw many people struggle with these as they couldn't "pinch" them to make a spout . . . lots of fluid was splashed around and not easily consumed.
So, I like to use a Nathan fuel belt thing (there are many different styles to choose from). I like mine because while I may only need two of the 10 oz. bottles for a 1/2, I'll use all four for a full. And it has a little flat pouch for my ID and keys. When I need calories as well, I bring a clip-on Hammer gel flask with approx. 1 Hammer Gel per hour in excess of one hour of running. My tummy doesn't like "gatorade"-type drinks, so the plain water and separate gel works well for me. I only learned this through lots of practice (and LOTS of potty stops) leading up to race day.
I know there are people who swear by walking through and drinking at the aid stations, but I like being able to bypass all the chaos and keep running. Plus, I get to drink/fuel on my own time-table rather than just when an aid station appears.
Anyway, everyone is different, so I really encourage you to practice until you find what is comfortable for YOU. This is great that you are thinking ahead.![]()
