The Cumbrian stage of the Tour of Britain brought £4.1million to the region.
An estimated 70,000 people lined the route to watch the world-class cyclists race, with 61 per cent coming from outside the region.
The first county-only stage of the tour began in September, running from Carlisle to Kendal. It included the gruelling king of the mountains stage at Honister.
The figure is almost double the £2.37million raised by the tour in 2012.
The findings were pulled together by economic experts Frontline for event organisers Sweetspot.
The Jedburgh to Dumfries leg of the 2012 Tour of Britain has won an award for the 'Best Sporting Event' at the Scottish Thistle Awards.
The awards ceremony, organised by VisitScotland, recognises the exceptional efforts made by companies and individuals across the industry, including accommodation providers, visitor attractions, tour operators, food and drink establishments and event organisers.
It was hosted by Lorraine Kelly on 15 November at Stirling Castle.
Alastair Grant, Commercial Director of SweetSpot Group, who organised and promoted the Tour of Britain, said:
"The Tour of Britain has been visiting Scotland and Dumfries & Galloway for a number of years with the event continuing to grow in stature and popularity, so are very proud to accept this award in recognition of our efforts."
The Tour of Britain cycle race has given our region a big economic boost.
The wet and windy weather took its toll in places, but official figures are expected to show that the stages between Peebles and Drumlanrig and from Carlisle to Kendal brought in millions of pounds.
Those in the tourism industry say the impact will be felt for years to come, and there are already talks about the race returning next year.

Competitors taking part in the Tour of Britain were given their biggest challenge yet when they were faced with tackling a very wet and windy Honister Pass in the Lake District.
The cyclists had to dig deep as they battled their way up the steep incline, which reached a 25% gradient in some places.
