Race fans will see big crowds of red Wednesday at Keeneland.
Guests are invited to wear the color for the track's 'Go Red' event.
Keeneland says the goal is to empower women with the knowledge they need to take charge of their health.
The American Heart Association will give out free red dress pins to the first 3,000 guests.
It says one out of three women die from heart disease.
Supporters can also order a special 'Go Red at Keeneland' package.
The cost is $15, which includes a general admission ticket and a special Go Red For Women gift.
Keeneland says it will donate part of the ticket price to the American Heart Association.
Race fans can order the package by calling 859-977-4601.
