Jaden Merrick, un niño de 6 años, corre un 5k en 22:26
El pasado fin de semana Jaden Merrick, un niño de sólo 6 años, corrió en Waterloo (Iowa), una carrera de 5 kilómetros en 22:26, batiendo por un minuto y medio el récord de su edad que tenía él mismo desde el pasado 2 de agosto.
Jaden lleva corriendo desde los 3 años y parece que no se le da mal, pero el debate se vuelve a abrir, ¿es sano hacer estos esfuerzos a edades tan tempranas? Correr un 5K en 22:26 supone ir a una media de 4:29 por kilómetro, en un cuerpo que no está aún ni mucho menos desarrollado. Pero bueno, es un 5K, no es la burrada de correr un maratón con apenas 5 años en 5h25:09 o de media maratón también con 5 años en 3h02:57.
Según el padre de Jaden: «Le encanta correr y nunca le hemos obligado a hacerlo. Desde que se enteró de que existían los cronómetros no ha dejado de tomarse tiempos corriendo alrededor de la casa y con 4 años ya nos pidió que lo lleváramos a carreras».
En la actualidad, Jaden corre de 15 a 30 kilómetros por semana y también hace de 30 a 50 kilómetros de bicicleta.
¿Quieres ser como el? Entonces debes elegir las zapatillas adecuadas para usar, aquí te dejamos algunas de las que consideramos las mejores:

La New Balance 1500 v4 es la cuarta versión de la zapatilla mixta que ha impresionado a todos los runners por su ligereza (en torno a 230 gramos) y ultra-estabilidad. En la media suela con Revlite, un material de amortiguación con muy buena respuesta, podemos encontrar una estructura hecha de una goma com más densidad para controlar la pronación y sobre todo para dar estabilidad al arco.
Sin embargo, los corredores neutros también podrán utilizar la 1500 v4 sin problemas. El agarre es fabuloso y el ajuste con Fantom Fit muy transpirable y agradable al tacto. Ideal para tus entrenamientos diarios si te gusta el drop natural de 6 mm y hacer segmentos rápidos. Para carreras, la 1500 v4funciona muy bien en largas distancias, sobre todo maratón. Una de las mejores zapatillas del momento.
La Nike Lunarglide 9 tiene un perfil un poco más blando que la 1500, con una amortiguación fundamentalmente basada en Lunarlon. Las transiciónes son suaves y consistentes, con la base más ancha del tobillo y la suavidad sobretodo en el medio de la zapatilla, garantizando que estés siempre centrado. El soporte para el arco del pie es bueno y puedes poner plantillas. La Lunarglide 9 es ideal para la maratón si tu objetivo está entre las 3:30 y las 4 horas o para entrenamientos en ritmos medios.
La Mizuno Wave Inspire 14 viene con un upper completamente renovado en funcionalidad y estilo. Las costuras y adhesivos están mejor colocados para evitar rozaduras en el arco del pie y aportar mayor resistencia a la parte delantera. En el exterior, Mizuno ha añadido revestimientos de mejor calidad y un poco más de branding. El resultado es una zapatilla más cuidada pero también más pesada. La amortiguación cuenta con la goma U4ic que le da un comportamiento más suave en la carrera. La Mizuno Wave Inspire 14 es una buena elección para aquellos que buscan un equilibrio entre estabilidad y confort.
La Adidas Solar Glide ST 19aporta el StableFrame, un material más firme que se encuentra por debajo del arco del pie. La combinación de Boost y el StableFrame ofrece transiciónes de primera calidad. Por un lado, el Boost aporta más respuesta y retorno de energía, por otro, el StableFrame compensa con estabilidad y consistencia en la pisada.
Cabe destacar también la increíble durabilidad de la suela, gracias a la goma Continental.
Tiene el MEJOR (y mayor) soporte del arco del pie de esta lista, algo evidente a simple vista. La mediasuela que está en contacto con el arco del pie (en torno al 20% de la misma) es más gruesa, haciendo que la transición de pisada del talón al dedo sea especialmente estable. La plantilla también se eleva 2 mm en su punto más alto, para ayudar a colocar correctamente el arco.
Es una zapatilla para pronadores peso mediano o pesado que quieran disfrutar del mejor confort. Un modelo lleno de tecnología, algo que se refleja en el precio. Aún así, la Kayano 25 es la mejor zapatilla del mercado para pronadores moderados, fantástica para pies planos —sobre todo, si el corredor es taloneador— y, por si fuera poco ¡brilla en la oscuridad!
Aunque está clasificada como una “zapatilla para pronadores”, la Transcend 5 también sirve para corredores con pisada neutra porque su control de estabilidad no va más allá de un excepcional soporte para el arco. Su mayor peculiaridad y valor añadido es el acolchado extra que proporciona el calcetín interior con correas de apoyo —justo debajo del arco— que envuelve el pie, proporciona una agradable sensación de confort y eleva el arco.
La New Balance 860 v8 es un valor seguro, un modelo que genera pocas sorpresas edición tras edición, pero que sin duda funciona para corredores pronadores. Es cómoda, fiable y con una mediasuela contundente. En esta versión se ha hecho un poco más blanda, con un pelín más de amortiguación y con una mejora en la transición de la pisada. Es ideal para corredores con pies planos de más de 70 o 75 kilos que quieran una zapatilla fiable y durable para los entrenamientos.
Brooks vende estás zapatillas asegurando que proporcionan “amortiguación, apoyo y estabilidad por partes iguales”. Ofrece una pisada firme y estable, gracias a una maya endurecida en la parte posterior con 4 densidades de espuma unidas sin adhesivos. Puede usarse con plantillas, lo que la convierte en uno de los modelos favoritos entre los pronadores.
