Organisers of this year's Mud Runner Lite have confirmed the event has been cancelled.
It had been due to take place at Eastnor Castle near Ledbury next month.
In a statement, event organisers said: "We were excited about bringing back this much loved event but unfortunately the sales have been slower than we expected and after the year we have had we simply cannot take the risk financially."
"Thank you for all the enthusiasm and love and especially to all of those who signed up. We have enjoyed your memories and all your comments."
"We will be giving everyone who has registered a full refund over the next week."
