The Canning Vale businessman is preparing to tackle the Tumbulgum Natural Terrain Motocross track in Byford on April 27 and 28 in the lead-up to the ground’s annual motocross event.
Mr Thomson will spend weeks fertilising the field ready for reconstruction, which takes about three weeks.
In this time, alongside his son Bryce, Mr Thomson will remove topsoil, carve out the racetrack with mechanical equipment, flatten the surface, place the topsoil back onto the track and complete the process with a layer of fertilisers and water.
Mr Thomson rebuilds the motocross track from scratch every year and prides himself on making the circuit different each time around.
This year, the track will be about 2km in length and will stick to a basic layout, meaning no jumps or sharp turns.
‘I always look at the tracks as if they were someone’s garden,’ he said.
‘You always have ideas of how you would change it and that’s how I got into designing racetracks. I wanted to put my ideas into practice.’
