Two Minutes That Take a Year to Prepare

The Kentucky Derby has been run at Churchill Downs every year since 1875 — the longest continuously held sporting event in the United States. The race itself lasts about two minutes; the festival around it runs two weeks.

The clock: Louisville keeps Eastern Time despite sitting in Kentucky, which is split between two zones. The Louisville Slugger bat factory here has made bats since 1884.
