I have my first half marathon coming up. How many people actual use fuel belts during half marathons? They will have aid stations but I'm not sure if having small bottles that are easy to drink out of during the run will be more helpful?

One thing that hasn't been mention is if this is a "green" half marathon. I have done a couple of trail half marathons that didn't have any cups on the course. If you wanted water you had to bring your own bottle, when you ran out you could refill your bottle at the aid stations.

I use a fuel belt w/ 2-8 ounce bottle(1 w/ water, 1 w/ flat coke or flat red bull).

I do this for several reasons:

-I'm 172 lbs and my 1/2 marathon pace in low 6:40's or high 6:30's; based on my weight and fitness level, I sweat a lot, so it helps
-With my bottles, I cab slow down to a light jog and take sips, to do this with aid station cups I have to completely walk. Some people may not think this is a big deal, but the more you slow down the more effort you have to put out to get back to your ideal pace
-Aid stations can be crowded
-I like having my fluids on me for whenever I want them

Also,a fuel belt will not slow you down; I barely notice mine sometimes

only if you wear compression socks, visor, and a cape.

There is some evidence that some carbohydrates in your mouth, even if spat out, boost performance.
I like to put a Sport Bean in my mouth to melt for this purpose. If you want something, put some kind of gel in a small gel bottle and squirt a bit in your mouth from time to time. You can squirt a sip a water from the aid stations in your mouth to wet your whistle, if you want.
