After a more than 900km journey from the eastern Riverina, 175 hay-laden semi trailers arrived in the parched Northern Tablelands town on Australia Day - delivering much-needed fodder and even a drop of rain.

Wagga couple Barb Konstantakis and Shane Bourke have been hay runners before, but this year's trek was something special.

"This is our fifth run and it has to be the most amazing one yet," Ms Konstantakis said.

The run - led by Burrumbuttock's Brendan Farrell - began on Friday morning from the Walbundrie Showground and reached Armidale on Saturday afternoon.

Thousands of people gathered by roads along the route, which included Sydney's M7 Motorway and Pennant Hills Road, to support the cause.

"The amount of people that lined the streets was amazing," she said.

"Coming into Tamworth and then into Armidale itself, there were thousands of people, it was just incredible."

Ms Konstantakis said the run had become a passion for the couple and was "something little that we can contribute".

While she believed their contribution was small, the significant boost provided by the fodder delivery wasn't lost her.

"It's tear-jerking," she said.

"Even the guys on the radio as we were going in, like all the blokes [were saying] 'How good is this? This why it's all worthwhile'.

"You know, 175 trucks is a pretty awesome sight to see and [there was] just an amazing feeling felt by everyone.

"The hair stands up on your arms ... your stomach gets butterflies and it's just that feeling we're able to give a little bit back."

Ms Konstantakis said she had spoken with a number of farmers who were "very grateful" to be on the receiving end of the delivery.

"It's heartbreaking to listen to their stories, but ... you can hear their gratitude in their voices," she said.

The hay run works off a ballot system, which required those wanting assistance to detail just how much feed they needed.

Such was the need for help, Ms Konstantakis said organisers received more than 700 ballots within a 150km radius of Armidale.

"That's how desperate people are," she said.

Northern Tablelands MP Adam Marshall was there as the trucks arrived.

"It's astounding, and it looks like they've brought the rain with them too," Mr Marshall said.

"Hay and rain, you couldn't ask for anything more."

The hay runners joined Armidale residents for a drought relief concert, which was headlined by songstress Sara Storer, on Sunday.
