The race day will take place the day after the Isa Street Festival, all but confirming the busiest time of the year.

The Mailman Express race (named after Wally Mailman father of famous actor Deborah Mailman) showcases non-professionals riders on non-thoroughbred horses, racing against the clock in a one by one affair.

The day begins with seven regular horse races, followed by the Mailman Express at 7pm.

President of Mount Isa Race Club Mick Tully said this years races were extra strong.

"The first of seven races is this Thursday at 1:19 pm. All together we have 66 horse nominations averaging out to almost ten horses a race which are really good fields," Mr Tully said.

"We have trainers coming from all over Queensland with the gates opening at 11am."

Mr Tully said to keep an eye out for a few local horses.

"The Queensland racing season finished last month and Danny Ballard won the country championship again," he said.

"Tanya Parry who is a trainer from this region came second in the trainers premiership and Bobby Byers came fourth, so all round Mount Isa had a great season."

The Mailman event will be televised on Sky Racing and TAB betting will be permitted.

Prize money for The Mailman Express:

1^st - $7500

2^nd - $2850

3^rd - $1150

Fastest local horse - $3000
