Instrucciones de uso de la calculadora de ritmo de carrera



Descripción


El ritmo (minutos por kilómetro) y el tiempo de llegada son los dos datos más usados en el entrenamiento de carrera. Esta herramienta calcula ambos y además muestra los tiempos parciales, para que puedas comprobar tu ritmo con el reloj durante la carrera.

Cómo usarla


  • Modo 1 «Calcular ritmo según la marca»: introduce la distancia y el tiempo total (h:min:s) para obtener el ritmo y la velocidad

  • Modo 2 «Calcular marca según el ritmo»: introduce el ritmo objetivo (min:s / km) y la distancia para obtener el tiempo de llegada estimado

  • Arriba hay botones rápidos de 5 km, 10 km, media maratón y maratón; pulsa uno para rellenar la distancia automáticamente

  • Debajo del resultado se muestra el tiempo acumulado por kilómetro (cada 5 km en distancias largas)


    • Notas


  • La unidad de distancia es el kilómetro; la media maratón se calcula como 21,0975 km y la maratón como 42,195 km

  • Los tiempos parciales se calculan suponiendo un ritmo constante; en una carrera real hay variaciones, así que solo sirven como referencia previa

  • Todos los cálculos se realizan localmente en el navegador

    • ❓ FAQ

    How many kilometers are the half marathon and marathon calculated as?

    The half marathon is calculated as 21.0975 km and the marathon as 42.195 km, which are the official standard distances.

    What's the difference between pace and speed?

    Pace is how long it takes to run one kilometer, and a lower number is faster; speed is how many kilometers you run in an hour, and a higher number is faster. They are reciprocals of each other.

    Are the splits accurate?

    They are cumulative times based on an even-pace assumption, which is useful for checking whether your rhythm has drifted, but real races vary with terrain and energy levels.

    The Difference Between JS Formatting/Minification and Manual Code Cleanup: Which Is More Suitable

    The difference between JS formatting/compression and manual cleanup comes down to automation versus human judgment. Formatting and compression are handled in bulk by tools according to rules—fast and consistent; manual cleanup is more flexible, suited to scenarios with special naming conventions or complex logic. For everyday development and debugging, use tools first and save human effort for the parts that truly need judgment. Understanding what JS formatting and compression means helps you decide when to use it and when to stop.
