Correr Inteligente is a running coaching and education brand founded by Mario Castellanos, a coach with a degree in Physical Activity and Sport Sciences and more than ten years of experience helping athletes train effectively. Its approach combines structured training, strength work and applied sports science to help runners improve performance and personal bests while reducing injury risk, without requiring professional-athlete status or unlimited training time.

The central offering is the Correr Inteligente training program, designed for runners at different stages, from those starting out to those preparing to compete. Plans are adapted to each runner’s goals and circumstances, with an emphasis on sustainable progress, appropriate pacing and training with sound judgment. The website also offers a free runner-type assessment to identify potential areas for improvement, alongside training resources, calculators and information about results and client experiences.

Mario is the author of Aprende a Correr Inteligente, a practical guide to more purposeful training, and hosts a Spanish-language running podcast featuring techniques, interviews and training discussions.
