Ditto what Iontach said, and I'll add:

Fuel with what ever you fueled with for your long runs during training.

Not so sure about that, especially in the absence of other information.

13.1 miles can take someone 2.5 hours @ a 12 - 12:15 pace, which many folks, especially here in the Newbie section is a pace they run.

If someone has not been eating properly in the day/days leading up to the race, add a 2.5 hour work out, other conditions (hills, etc), glycogen stores could be an issue.

The 2.5 hour 12-12:15 pace scenario that you describe will burn little in the way of glycogen. A run at that pace and duration is fueled more by fat than carbohydrates. As your pace goes down the percentage of fat that you burn goes up. Walking for instance burns almost 100% fat. Of course poor eating habits could be an issue but unless someone is purposely restricting carbs as in a low carb diet, there will be plenty of fuel to complete a half marathon. A possible exception would be someone who is very fast as in an elite runner.
