LOUISVILLE, Ky. (WDRB) -- The U.S. Bank Great Balloon Rush-Hour Race took off Friday morning.

"The Great Balloon Rush-Hour Race is a Hare & Hound Race," the Kentucky Derby Festival's website states. "This type of race is when all the balloons launch from the same site (Bowman Field). One balloon takes off first and is the Hare balloon (U.S. Bank Balloon piloted by Scott McClinton). The other balloons are called the Hounds, and they launch at a predetermined time after the Hare (usually 5 to 10 minutes after).

The Hare lands at a suitable site and lays out a large fabric X, usually about 50 feet in diameter. The Hound balloons attempt to drop their markers as close to the center of the X as possible. The closest marker achieves the highest score."

More balloon events are scheduled through Saturday morning:

The U.S. Bank Great Balloon Glow returns to the Kentucky Exposition Center with 29 balloons on Friday night.  Gate open at 6 p.m.  At 9 p.m., the balloon pilots will fire burners to create the glow synchronized to music on radio station 106.9 Play.

The final balloon event is the U.S. Bank Great Balloon Race, which launches 25 balloons from Bowman Field Saturday at 7 a.m. The first Great Balloon Race was held in 1973.
