I’m a runner and I’ve been doing it for quite some time now (though I gotta admit that it has been slightly less due to the rain. In any case, runners are mostly aware of the importance of building up the glycogen stores before going for a run. But, there are foods that can cause stomach problems and other woes. So, avoid eating these foods to prevent that!
1. Fatty foods
Sure, fat as a macronutrient is an essential part of a balanced diet, but fatty foods before a workout are a definite no-go. Why? Because fat stays in your stomach because it takes longer to digest. It makes you feel uncomfortable during a run. A high rate goes for saturated fats like cheese, bacon, burgers etc.
2. Lactose
Not all runners can handle a glass of milk or bowl of yogurt before a workout. Why? Because lactose is a part of dairy products and often gives people trouble digesting it.
3. Legumes
Legumes are an ideal source of fiber for runners. You know, like beans or lentils. Though, eating high-fiber foods before a run can lead to gastrointestinal distress or diarrhea. The last thing isn’t nice whilst running. There’s isn’t exactly a toilet every mile you run.

4. Spicy foods
Eating spicy foods are a bad idea before running. Sure, they’re good for boosting your metabolism, but can cause heartburn or gastrointestinal distress.
5. White sugar
Carbohydrates are a good idea for preparing for a long run. But sugary foods like sweets or breakfast cereals aren’t. These are filled with empty calories, possibly hampering you. Your blood sugar spikes first, to then fall rapidly. This is known as hypoglycemia, which can lead to fatigue, headaches and a bad run. What you should eat instead, is a bowl of oatmeal or quinoa.
6. Protein bars
They seem healthy, but reality is that many protein bars are filled with refined sugar. Remember the previous one? Then you know this isn’t good for you. What you can do, is make your own homemade granola bar. This is a great way to build up your glycogen stores before a run.

7. Sports drinks
They often seem healthy, but are usually full of sugar. Point 5 proves why that’s bad. The best thing to do before, during and after a run is to drink water. Isotonic drinks aren’t necessary unless you’re planning to run for more than an hour. And even better, create your own sports drink.

Interesting about sports drinks. I’ll bear that in mind. I generally drink water with electrolytes as I’m doing long runs and am a high salt sweater (not a jumper haha)

That’s good! You know what you need to refill yourself, which isn’t so common for people to think about. You’re doing a great job!
