This is very cool activity/sport. Something between regular walking which is not hard enough and running which can be harder then it should be. But I would put an lower age limit to this competitions. No body younger than 40 years of age can not compete. It is ridiculous.
En circuitos en que se combina tramos de asfalto y otros de grava o tierra, ¿se ponen tacos de goma en la punta de los bastones o se corre sin tacos de goma?
