Running Addiction: When a Love for Running Becomes a Psychological Dependence

Introduction

“I feel off all over if I don’t run for a day.” “I sneak out for a run even when injured, because I get so anxious if I don’t.” “My family says running takes up all my time, but I just can’t stop.” These familiar-sounding words are not uncommon in Taiwan’s road-running community.

Running addiction (Exercise Addiction, or Running Addiction) is a topic that sports psychology has been increasingly focusing on in recent years. Research from the University of Leicester in the UK indicates that among actively training marathon runners, approximately 3–5% meet the diagnostic criteria for exercise addiction, while the proportion exhibiting “problematic running behavior” is even higher.

Running addiction is essentially a behavioral addiction whose psychological mechanisms bear significant similarities to substance addiction, yet because of running’s “healthy” facade, it is even harder for both the individual and those around them to detect.

Diagnostic Indicators of Running Addiction

If you meet 3 or more of the above criteria, it is worth seriously examining your relationship with running.

Primary and Secondary Running Addiction

Sports psychology distinguishes between two types of running addiction:

Primary Running Addiction: Running itself becomes the object of dependence, with the core drive stemming from the neurochemical rewards running provides (endorphins, dopamine).

Secondary Running Addiction: Running becomes a tool for controlling weight, body shape, or eating behavior, and is usually comorbid with eating disorders (such as anorexia nervosa or bulimia nervosa). This type has a higher proportion among female runners and requires more integrated psychological intervention.

Secondary running addiction is often harder to treat because it is connected to deeper body-image issues and cannot be addressed solely through “running behavior” itself.

The Psychological Roots of Running Addiction

Behind most cases of running addiction, identifiable psychological functions can be found:

• Emotional Regulation Tool: Running is the only effective method for coping with anxiety, stress, and feelings of emptiness. Once this tool is removed, the individual lacks alternative emotional coping abilities.
• Identity Fusion: “I am a runner” becomes the core of self-definition, and stopping running equates to a collapse of self-worth.
• Avoidance Mechanism: Running becomes a refuge for escaping relationship conflicts, work stress, or traumatic memories.
• Perfectionism: Treating the achievement of mileage goals as a quantitative indicator of self-worth.

Pathways to Rebuilding a Healthy Relationship with Running

1. Acknowledge the Problem Exists

The biggest obstacle to running addiction is society’s “encouragement”—when those around you praise your training commitment, the addictive behavior is continually reinforced. You need to deliberately pause these external rewards and examine your intrinsic motivation.

2. Expand Your Emotional Toolbox

Work with a psychologist to build emotional regulation strategies beyond running: mindfulness meditation, breathing exercises, social connection, creative expression, and more. Shift running from “the only outlet” to “one of the options.”

3. Experiment with Forced Rest

With safe support, try arranging a “no-running week,” observe your emotional responses, and learn to coexist with withdrawal symptoms. This serves as both diagnosis and treatment.

4. Redefine Success

Reframe “smart training” (including adequate rest) as part of running achievement, not laziness. Elite runners’ training plans include substantial rest—this is science, not an excuse.

Practical Advice

• Use the Exercise Addiction Inventory (EAI) for a preliminary self-assessment
• If you suspect secondary addiction, prioritize seeking help from a psychologist specializing in eating disorders
• Share your concerns with a trusted running partner; an external perspective is often more accurate than self-assessment
• Mental health centers in various cities and counties across Taiwan offer free initial consultations, and exercise addiction falls within their scope of services

Conclusion

Loving running is a wonderful thing, but love should not become a shackle. A true runner can not only run at full effort but also slow down gracefully, and even stop completely when necessary. Knowing when to stop requires greater wisdom and courage than persevering. If running has already taken away your freedom, it is time to take it back.
