With more than 50 federations and thousand of elite athletes The International Association of Ultrarunners came into existence in 1984.
Today there are more than a thousand ultra races around the world with more than a
hundred thousand ultra runners. It is no more an unrealistic event.
The IAAF granted its patronage to the IAU in 1988 and the 100km race became a
standard distance recognized by the Federation.
Today IAU organizes 4 major events: 100 km World Championship, 24 Hour World
Championship, The Trail World Championship and the 50 km World Trophy Final. IAU
is also a strong supporter of the Commonwealth Championships. This is in addition to the
IAU labels that are attached to several races around the world.
With more than 50 federations and thousand of elite athletes having participated in its
events over the years, IAU has respectfully upheld its mandate of developing the sport of
ultrarunning.
While it continues to serve the ultrarunning community, the IAU is looking forward to
the next 24 years as it envisions reaching its 50th Anniversary.
