Hiking is a recreational activity which consists of taking long walks in outdoor environments. The activity of hiking is often performed on hiking trails that generally requires the use of special footwear, such as hiking boots, that can provide support, stability and traction on rough terrain. When hiking, the use of the appropriate hosiery can also help prevent blisters, distribute pressure and absorb shock making the experience of hiking more enjoyable.
Running is both a competition and a type of training for sports that have running or endurance components. As a sport, it is split into events divided by distance and sometimes includes permutations such as the obstacles in steeplechase and hurdles. Running races are contests to determine which of the competitors is able to run a certain distance in the shortest time. Today, competitive running events make up the core of the sport of athletics. Events are usually grouped into several classes, each requiring substantially different athletic strengths and involving different tactics, training methods, and types of competitors.
