Even though, the temperatures were on the cool side this Saturday, it still gave officials at the Bluegrass State Games a chance to test a new device designed to alert them when athletes get too hot.
The precaution comes after the death of Jefferson County football player Max Gilpin from heat exhaustion last summer.
Pleasure Ridge Park head coach Jason Stinson is charged with reckless homicide in the death of the 15-year old.
Gilpin's death prompted lawmakers to take action.
And even on a cool day like Saturday, danger lurks.
A new device has been developed called the "I-dot," which changes color from black to bright yellow when the wearer's core temperature reaches 103 degrees.
Heat exhaustion occurs at 104 degree and stroke at 106.
The typical heat stroke occurs between 72 and 85 degrees, outside temperature.
The disposable "I-dot" will sell for somewhere between 25 and 35 cents per patch.
But right now, the product is still in the testing phase and not yet available to the public.
