Mackston Leopard, known as Mack by his friends and family, began his racing career at 9 years old at Kil-Kare Raceway in Xenia, Ohio.

Starting off in the quarter-midget ranks, Leopard became a regular fixture at tracks around the region, even going so far as to compete in five different divisions on the same day.

His time in quarter midgets resulted in a pair of championships in the Midwest Thunder Racing Series, where he claimed titles in the Senior Honda and Light 160 classes.

In 2023 Leopard signed with CB Industries, the powerhouse open-wheel team owned by Chad Boat, and began racing Micros across the United States. He scored three wins in 2023 at Millbridge Speedway located in North Carolina and US 24 Speedway in Logansport, Indiana.

He backed that up in 2024 with several huge wins, including a $5,000 win during the Tom Rieck Memorial at Coles County Speedway.
