Mullaley will be overrun with athletes of all shapes and sizes on June 14.
The public school has won the vote to host the north west area cross country, with primary and secondary students to bus in from all over the region to compete.
Twelve of Mullaley's own students will be among the competitors, with the races to start and finish in the school grounds.
Principal Ben Carter said he expected about 1500 competitors aged 8-18 years from towns including Moree, Armidale, Coonabarabran, Quirindi and Tamworth.
Mr Carter it was the first time the school had hosted a cross country event and it would draw visitors to the area.
"It's a good thing both for school and community with the added profile it's given school and added opportunity for local businesses to benefit from this - not only Mullaley but Gunnedah - through accommodation," he said.
Preparations are well under way, with the school community completely on board, even providing accommodation to Lightning Ridge students.
"We're seriously working away to make sure we've got enough food for it, and we've got parents coming in and making sure the course is up to scratch," Mr Carter said.
"It is an exciting time for [our students]. They like to showcase our school."
