Colorado State Fair officials are considering scaling the event back to 11 days from 16.
Assistant Manager Chris Wiseman says board officials want to see whether the fair can be more profitable and sell out more performances by trimming the schedule.
No decision will be made until the board's Nov. 25 meeting.
Wiseman says this year's 16-day event made about $900,000. But he says the fair has lost money since 1997 based on its year-round operations.
The fair last had an 11-day run in 1990 when board officials decided to expand to 17 days to ease crowding and help vendors make up for bad weather.
