But the imposing tower of fodder is not your average mud run obstacle – by any means.

Rather it forms part of an ingenious plan by Suck It Up Buttercup Mud Run organisers to support local farmers doing it tough during the drought.

The massive hay bales, which sit four feet high by eight feet long, are available for purchase for $150 each ahead of the May 3 challenge at AELEC.

And for digging deep and lending a hand, generous businesses or mud run teams will have their name displayed on a corflute banner attached to their “bale” before and during the event.

Race director Peter Mannings said the ‘Stack ‘em up’ initiative was “about giving back to the farming community that support us in so many ways”.

“We have some tremendous support already on board with the likes of McDonald Bros Transport, Llyod Sign Co, 2Creative Media, Tamworth Regional Council and Mitchel Hanlon Consulting,” he said.

“With 13 bales already sold...we are well on our way to building one of the biggest hay bale towers seen at an obstacle race.”

On Sunday, May 11 there will be a hay handover and sausage sizzle at AELEC where all businesses and people who have donated a hay bale will be invited to come along to help present the bales to local farmers.

“The more businesses that get on board the more hay we can get to give away,” Mr Manning said.

Suck It Up Buttercup’s inaugural 10km mud run challenge last November attracted more than 2000 entrants.
