Alan Mason and Jim Gilbert say an accident is going to happen on day if people continue to use the grass as a racetrack.
Drivers taking their cars off-road and onto the grass at Te Kapua Park are regularly causing damage.
Stratford racing club life members Alan Mason and Jim Gilbert say as well as the damage caused, they have concerns about the safety of those involved.
"There are horses and sheep in the
area, often on the very grass they are ripping up with their tyres. One day someone is going to damage themselves as well as the turf."
Jim says there is no lighting in the area, as it isn't a road, and at night it would be easy for someone to not see a hazard until it is too late.
"The people coming here to hoon around in their cars are taking risks as well as showing no respect for the grounds. They deliberately open the gates on their way to the grass, so they are well aware they are trespassing."
