Join in the fun with a Charity 1980s Day at the Castle Sports Complex in Spalding on Wednesday (7am-10.30pm).
Staff are dressing up and classes and facilities are being offered free.
Staff at the complex are asking for donations in return for raffle tickets to win prizes.
The event is in aid of Macmillan Cancer Support and WheelPower, which helps those with disabilities to rehabilitate through sport.
There’s a surprise in store for the class that meets at 6pm for legs, bums and tums!
