LOUISVILLE, Ky. (AP) — Miles of dirt trails, jumps and stunt courses for bikes are being built inside an abandoned Louisville mine.
The owners of the new bike park inside the mine say it'll be the largest indoor bicycle course in the nation. It's part of Louisville's Mega Cavern, an underground business park that has in recent years become a tourist attraction with zip lines and Christmas light shows.
The new bike park stretches out over five football fields. It's about three times the size of the next-largest indoor park, Ray's MTB in Cleveland.
Co-owner Tom Tyler says the mine offered the perfect layout for a bike park, and they had plenty of dirt to spare. It will also stay a constant 58 degrees inside.
It's set to open to the public in March.
