Colin Reffner
Third-generation racer.
Wisconsin short-track champion.
Colin Reffner comes from a racing family with deep roots in Wisconsin motorsports.

A Racing Family
Colin Reffner did not stumble into motorsports. He was born into it. Racing runs three generations deep in the Reffner family, and that legacy shapes everything about how Colin approaches his craft, from the way he prepares to the way he carries himself at the track.
Growing up in Wisconsin Rapids, Colin learned early that racing is not just a sport in the Reffner household. It is a way of life. The discipline, the work ethic, and the respect for the craft were passed down long before he ever sat behind the wheel of a race car.
That foundation shows in how Colin has built his career. He did not take shortcuts. He started at the bottom, earned his Rookie of the Year honors in 2011, and spent the next decade-plus grinding through the Wisconsin short-track ranks. Every championship, every fast qualifier award, and every race win along the way was built on preparation and consistency rather than circumstance.
The family connection to Wisconsin motorsports is not just history. It is present in every race weekend, every setup decision, and every moment Colin straps into a race car. If you’ve been to a Midwest short track race since you were little, it would be a challenge to not see the Reffner name imprinted somewhere at the track.
Looking Ahead
The 2026 Midwest Truck Series season may see Colin Reffner behind the wheel of the #31 Thirty One Motorsports Ford for select races across the 14-race schedule. After years of building his resume on Wisconsin’s most competitive short tracks, Reffner steps into the series ready to run at the front and make his presence known at every stop on the schedule. Whether he turns a lap on the race track or not, you can always catch Colin on social by watching his Speed & Grease podcast.
