Description: Sprinting is running over a short distance at the top-most speed of the body in a limited period of time. It is used in many sports that incorporate running, typically as a way of quickly reaching a target or goal, or avoiding or catching an opponent. Human physiology dictates that a runner's near-top speed cannot be maintained for more than 30–35 seconds due to the depletion of phosphocreatine stores in muscles, and perhaps secondarily to excessive metabolic acidosis as a result of anaerobic glycolysis.

Description: Mountain running is a sports discipline which takes place mainly off-road in mountainous terrain, but if there is significant elevation gain on the route, surfaced roads may be used. In this it differs from fell running; also its courses are more clearly marked and avoid dangerous sections. It is a form of trail running if it is run on unpaved surfaces. Mountain running is a combination of running, jogging, and walking, depending on how steep the trail is.

Description: Trail running is a type of running that takes place on outdoor trails, often in mountainous terrain, and often includes significant ascents and descents. Trail running is overseen by the International Trail Running Association (ITRA) and includes longer races. It is similar to both mountain and fell running (also known as hill running). Unlike road running and track running, it generally takes place on outdoor trails, often in mountainous terrain, and often includes significant ascents and descents.

Description: The marathon is a long-distance foot race with a distance of 42.195 kilometres (c. 26 mi 385 yd), usually run as a road race, but the distance can be covered on trail routes. The marathon can be completed by running or with a run/walk strategy. There are also wheelchair divisions. More than 800 marathons are held worldwide each year, with the vast majority of competitors being recreational athletes, as larger marathons can have tens of thousands of participants.
