I keep getting injured whenever I increase my running

Part of injury risk is genetic, variants in collagen genes like COL1A1 affect tendon and ligament resilience, which is why some bodies tolerate high mileage and others break down.

Why it happens

Collagen-related genes influence how your connective tissue handles repeated load. If you carry lower-resilience variants, ramping mileage too fast is more likely to end in a niggle. It does not mean you cannot run, it means a slower safe progression and non-optional strength work around the joints.

One thing to try

Increase your weekly running distance by no more than ten percent. Boring, and the single best way to stay uninjured.

Each decode is a research-backed tendency, not a diagnosis. A tap tells you how your body is likely wired and what to try, it does not label you, and nothing here is a substitute for a doctor where a medical question is involved.
