A Midsummer Night's Run will mark its 25th anniversary Saturday night.
Festivities include a 1-mile walk/run at 6 p.m., a "Fastest Kid in Town" sprint competition at 6:35 p.m., and the featured 5-kilometer (3.1-mile) race at 8:30 p.m.
Central Baptist Hospital sponsors the event "to promote healthy lifestyles and fitness in families and communities around the Bluegrass."
Beginning at noon, there will be activity centers near Vine and Mill streets, where the start and finish lines are located and where late registrations ($25) will be accepted outside the Lexington Downtown Hotel.
The 1-mile kickoff is considered a casual event and is open to all ages, including babies in strollers.
The Fastest Kid in Town, for ages 1 through 12, consists of sprints of 20 yards to 60 yards.
The 5-kilometer race is competitive, although joggers and walkers also turn out.
