5 Things Not to Do Before Running: Essential Tips for New Runners to Avoid Injury from the Start

Recently, the health trend is gaining momentum, and many people are starting to “ run ” to take better care of themselves, whether running in parks, on treadmills, or preparing for marathons. But did you know that “preparing before running” is just as important as running itself? Small habits can limit your performance or, worse, put you at risk of injury without realizing it.

Thairath Online recommends 5 Things to Avoid Before Running That You Should Know to help prepare your body and run confidently in a healthy way.

Here are 5 things you should not do before running to prepare your body and run healthily with confidence.

Good running isn’t just about distance or speed but about taking care of your body before you start. Avoiding these behaviorswill help yourun more comfortably, recover faster, and clearly reduce the risk of long-term injury.

1. Do Not Eat a Full Meal Before Running

Eating a large meal, especially shortly before running, often causes bloating, cramps, or discomfort while running because your body must divert energy to digesting food instead of fueling muscles. If you must eat, choose light, easily digestible foods and wait at least about one hour before running, such as a banana or a small amount of carbohydrates. Avoid high-fat foods, fried items, and heavy sweets to prevent overworking your digestive system.

2. Do Not Hold Static Stretches Before Running

A common misconception is to hold static stretches before running, but this method is actually better suited for after running. Before running, focus on dynamic warm-ups like brisk walking or light jogging for about 5–10 minutes to stimulate blood flow and improve muscle flexibility. This approach helps your body adjust and reduces injury risk.

3. Don’t Neglect Bowel Movements Before Running

Another often overlooked issue is neglecting to manage bowel movements before running, especially in the morning. Experiencing stomach pain mid-run can disrupt your pace and confidence immediately. Training your body to have regular bowel habits reduces worries and makes running smoother. This small detail significantly enhances the running experience.

4. Avoid Drinking Excessive Water

Drinking too much water before running can cause fullness or stomach discomfort, while drinking too little risks dehydration and fatigue. The right approach is to sip water moderately and steadily before running, avoiding beverages high in caffeine or sugar as they may increase heart rate or cause energy fluctuations during running.

5. Don’t Force Running When Your Body Isn’t Ready

Discipline is good, but pushing your body beyond its limits isn’t the answer. If you feel tired, haven’t slept enough, or have accumulated soreness, running may worsen your condition. Good runners learn to listen to their bodies, distinguishing between “laziness” and “genuine unpreparedness.” Resting when needed is part of building long-term strength.

However, if you plan to participate in races, pay attention to your diet 2–3 days in advance by avoiding fried foods, spicy dishes, milk, or strong coffee, and refrain from trying new foods during this period to keep your digestive system steady. Otherwise, it could affect your health or digestion and cause you to miss scheduled running events.
