The International Association of Ultrarunners (IAU) is operating under the patronage of the IAAF and is dedicated to develop ultradistance running internationally within the IAAF Rules & Regulations.

As international governing body for ultradistance running, one of our main objectives is to promote and develop long distance running worldwide by encouraging specific activities in each of the IAAF Continental Areas.

The 100 km is our “flagship” since the IAAF officially sanctions this distance and also ratifies 100 km world records.

The major IAU competitions are :
100 km World Championships under the patronage of the IAAF
100 km Area Championships
24H World Championships
24H Area Championships
Trail World Championship
50 km World Championship
