Whois & Analysis for roka.com

A triathlon is a multiple-stage competition involving the completion of three continuous and sequential endurance disciplines.

While many variations of the sport exist, triathlon, in its most popular form, involves swimming, cycling, and running in immediate succession over various distances.

Triathletes compete for fastest overall course completion time, including timed "transitions" between the individual swim, cycle, and run components.

The word "triathlon" is of Greek origin from τρεῖς or treis ("three") and ἆθλος or athlos ("competition").

Cycling, also called bicycling or biking, is the use of bicycles for transport, recreation, exercise or sport.

Persons engaged in cycling are referred to as "cyclists", "bikers", or less commonly, as "bicyclists".

Apart from two-wheeled bicycles, "cycling" also includes the riding of unicycles, tricycles, quadracycles, recumbent and similar human-powered vehicles (HPVs).

Glasses, also known as eyeglasses or spectacles, are devices consisting of glass or hard plastic lenses mounted in a frame that holds them in front of a person's eyes, typically using a bridge over the nose and arms which rest over the ears.

Glasses are typically used for vision correction, such as with reading glasses and glasses used for nearsightedness.

Safety glasses provide eye protection against flying debris for construction workers or lab technicians; these glasses may have protection for the sides of the eyes as well as in the lenses.

Some types of safety glasses are used to protect against visible and near-visible light or radiation.

Glasses are worn for eye protection in some sports, such as squash.

Glasses wearers may use a strap to prevent the glasses from falling off during movement or sports.

Wearers of glasses that are used only part of the time may have the glasses attached to a cord that goes around their neck, to prevent the loss of the glasses.

Clothing (also called clothes and attire) is fiber and textile material worn on the body.

The wearing of clothing is mostly restricted to human beings and is a feature of nearly all human societies.

The amount and type of clothing worn depends on body type, social, and geographic considerations.

Some clothing types can be gender-specific.

Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot.

Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions).

This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion.

A characteristic feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity.

The term running can refer to any of a variety of speeds ranging from jogging to sprinting.
