The Global Positioning System (GPS) is a space-based radionavigation system owned by the United States government and operated by the United States Air Force.

It is a global navigation satellite system that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.

The GPS system operates independently of any telephonic or internet reception, though these technologies can enhance the usefulness of the GPS positioning information.

The GPS system provides critical positioning capabilities to military, civil, and commercial users around the world.

The United States government created the system, maintains it, and makes it freely accessible to anyone with a GPS receiver.

However, the US government can selectively deny access to the system, as happened to the Indian military in 1999 during the Kargil War.

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").

Heart rate is the speed of the heartbeat measured by the number of contractions of the heart per minute (bpm).

The heart rate can vary according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide.

It is usually equal or close to the pulse measured at any peripheral point.

Activities that can provoke change include physical exercise, sleep, anxiety, stress, illness, and ingestion of drugs.

An activity tracker, also known as a fitness tracker, is a device or application for monitoring and tracking fitness-related metrics such as distance walked or run, calorie consumption, and in some cases heartbeat and quality of sleep.

The term is now primarily used for smartwatches that are synced, in many cases wirelessly, to a computer or smartphone for long-term data tracking.

There are also independent mobile and Facebook apps.

Some evidence has found that the use of these type of devices results in less weight loss rather than more.

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).
