An ultramarathon, also called ultra distance or ultra running, is any footrace longer than the traditional marathon length of.

In sport, racing is a competition of speed, against an objective criterion, usually a clock or to a specific point.

The competitors in a race try to complete a given task in the shortest amount of time.

Typically this involves some distance, but it can be any other task involving speed to reach a specific goal.

The 10K run is a long-distance road running competition over a distance of ten kilometres (6.2 miles).

Also referred to as the 10K road race, 10 km, or simply 10K, it is one of the most common types of road running event, alongside the shorter 5K and longer half marathon and marathon.

It is usually distinguished from the 10,000 metres track running event by stating the distance in kilometres, rather than metres.

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.

Trail running is a sport which consists of running and hiking over trails.

In the United Kingdom and Ireland it is called mountain or fell running.

It differs from road running and track running in that it generally takes place on hiking trails, often in mountainous terrain, where there can be much larger ascents and descents.

It is difficult to definitively distinguish trail running from cross country running.

In general, however, cross country is an IAAF governed discipline that is typically raced over shorter distances (rarely over 12 kilometers), whereas trail running is loosely governed, and run over longer routes.
