Heel pain, or heel spurs are characterized by sharp pain within the heel that often stems from the arch. The most common cause of heel pain is plantar fasciitis. People with plantar fasciitis have a heel spur on the front and bottom of their heel.
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.
