Running seems simple: one foot in front of the other. But behind that simplicity lie dozens of decisions that affect your performance, your health and your enjoyment. These are the 10 mistakes we see over and over in the CorrerJuntos running groups, and how to fix them (World Athletics) (WHO).
1. Too much, too soon
High injury riskThe number one mistake. Going all-out on every run, piling on miles every week with no control, jumping from zero to a half marathon in 2 months. Your cardiovascular system adapts fast, but your tendons, ligaments and bones need months to strengthen.
2. Wrong shoes
High injury riskRunning in indoor soccer shoes, worn-out trainers with no cushioning left, or a model that doesn't match your gait. Your shoes are the only thing standing between you and the repeated impact of the pavement (ACSM).
3. Skipping the warm-up
Medium riskWalking out the door and hitting race pace from step one. Your muscles, tendons and joints need a transition from rest to activity. Running cold increases your risk of strains and overload injuries.

High injury riskThinking more is always better and running every single day without a break. Your body doesn't improve while you run -- it improves while you rest. Training provides the stimulus; rest produces the adaptation.
5. Poor hydration
Medium riskBoth dehydration (not drinking enough) and overhydration (drinking too much plain water during long runs without electrolytes) are dangerous and affect performance.
6. Neglecting strength training
Medium riskBelieving that to run better you only need to run. Strength work strengthens stabiliser muscles, improves running economy and prevents injuries. You don't need a gym -- bodyweight exercises are enough.
7. Comparing yourself to others
Low risk (but frustrating)Seeing other people's paces on Strava and feeling like you're too slow. Every body is different: age, genetics, years of training, past injuries... The only valid comparison is with yourself three months ago.
8. Poor nutrition
Medium riskNot eating enough before a long run, failing to refuel after a hard workout, or following restrictive diets that don't support running. Your body needs fuel to perform and recover.
9. Always running the same way
Low risk (but leads to stagnation)Going out at the same time, on the same route, at the same pace, every single time. Your body adapts and stops improving. Physical stagnation leads to mental boredom.
10. Always running alone
Low risk (but affects motivation)Running solo has its perks, but doing it ALL the time is the mistake that causes the most runners to quit. Without social accountability, without external motivation, without the energy of a group, it's easy to stay home when it rains, gets cold or you just don't feel like it.
