UltraRunning is devoted to covering the
sport of long distance running, also known as ultramarathoning, or, as
we prefer, ultrarunning. How far is "a long distance"? The standard
definition is anything past the marathon, or 26.2 miles. However, the
shortest standard distance that is considered an ultra is the 50
kilometer distance, or 31.07 miles. Other standard distances are the 50
mile, 100 mile, 100 km, and a series of events that last for specified
time periods such as 6 hour, 12 hour, 24 hour, 48 hour, and 6 days.
Occasionally, we extend our editorial coverage to include
shorter distances if they merit the tag of "something different;" such
races might involve considerable difficulty involving severe terrain,
or perhaps a route requiring some navigational abilities.
