Which means the answer to your first question is: "No, you don't need to carb load for a 5K." That said, carbohydrates are still the optimal fuel for working muscles, so while in training you still want to eat a daily diet that is rich in carbs, moderate in protein, and low in fat.
How many carbs do you need to run a 5K?
Fueling an endurance athlete through training and racing requires about 2.5-4.5 grams per pound of body weight, or 55-65% total diet from carbohydrate (compared to 2.5-3.0 grams/pound for moderate exercisers and more than 4.5 grams/pound for ultra endurance athletes).
What should you eat before running a 5K?
Keep it simple—a bowl of oatmeal with dried fruit, a sports bar, bagel with peanut butter. Eat something high energy and easily digestible. Be sure to include hydration—water, sports drink if it's warm outside to give you the electrolytes you need, and coffee if that's part of your normal routine.
