Draft:Global Organization of Multi-Day Ultramarathoners

The Global Organization of Multi-Day Ultramarathoners (GOMU) was founded in October 2021 to recognize Multiday race World Records that are not recognized by the International Association of Ultrarunners.

History
In September 2021, the International Association of Ultrarunners announced the removal of several multiday events being recognized as IAU World Records, including the six-day event that has historical significance dating back to the 1700s. After an uproar by Ultramarathon historians and runners, the IAU admitted their mistake and added back six-days, which is recognized as an IAU World Best. However, 1000km and 1000 miles are no longer recognized by the IAU as World Records or Bests.

GOMU was created to recognize the IAU-ratified World Records for 48 hours and 6 days, along with many other multiday records. They recognize standard times/distances for 48 hours, 72 hours, 6 days, 10 days, 500 miles, 1000 miles, 2000 miles, 3000 miles, 3100 miles, 500 km, 1000 km, 2000 km, 3000 km, 4000 km, and 5000 km. They also recognize records for a number of non-standard formats (4 days to 49 days, 200 miles to 2900 miles, and 300 km to 4900 km).

GOMU was also created to host World Championships for 48 hours and 6 days, "...to encourage multi-day athletes from many nations and of all calibers to come together to compete on a level playing field and to aspire after world, national, age group, and personal records." The first GOMU 48 hr World Championship was held in Sept. 2022 in Hainsport, NJ.
