Leading riders and novices alike are competing over three days at the Lincolnshire Horse Trials at the Lincolnshire Showground.
The three-day event runs March 18-20 and is organised by Bishop Burton College and the Lincolnshire Agricultural Society.
Each day, riders focus on a particular event so that visitors can enjoy cross country, dressage and show jumping.
The sport is run much like a triathlon, combining different disciplines in one competition and running on a cumulative penalty basis.
The admission price for spectators is £5 per car, including all occupants. Find out more about tickets on the Bishop Burton College website.
