It depends on the individual and the type of run they are planning to do. Generally speaking, it's a good idea to eat a light meal or snack before a run to provide your body with the energy it needs to perform. However, you don't want to eat a heavy meal right before your run, as this can lead to digestive issues and discomfort while running.

If you're planning a shorter, low-intensity run, you may not need to eat anything beforehand. However, if you're planning a longer or more intense run, it's a good idea to eat a small snack containing carbohydrates and some protein at least 30 minutes before your run to give your body the fuel it needs to perform.

Ultimately, it's important to listen to your body and experiment to see what works best for you. Some runners may find that they need to eat a full meal a few hours before a long run, while others may prefer to run on an empty stomach.
