Randy Belding credits his son Jay for the inspiration behind BluTrack.
Belding and his 4-year-old son were playing with a racetrack that kept malfunctioning. Despite countless tinkering, Jay would walk away bored after two loops.
"Jay was disappointed with his racetrack, but I realized how much fun I had with him just trying to make the track work," Belding said.
So he spent two years creating and improving on different versions. In 2006, Belding co-founded MJ Sports and launched BluTrack, a line of bendable two-way racetracks made from flexible PVC.
The pieces come in three lengths and can be twisted and looped in a variety of ways. Belding said he's sold around 30,000 BluTracks in the last six years, mostly through specialty stores and online.
"One of the biggest struggles is trying to get kids to play with a toy for a long time," he said. "This is such a simple concept and it lets kids use their imagination."
