The Wiltshire Weekender, an event organised by British Cycling, will bring together sportive riding and professional road racing on the second weekend of August.
The Salisbury Sportive will be held on Saturday August 11, offering routes of 60 and 100 miles, both of which start in Salisbury and pass through Hampshire and Wiltshire.
The following day, Sunday August 12, the final round of the elite category Premier Calendar series will be held on two circuits that will take the riders through Wilton 10 times.
A British Cycling spokesman said the governing body hoped to announce a new sponsor for the event, backed last year by Twinings, within the next three weeks.
