The Tour de France's visit to the UK this summer was watched by crowds totalling 4.8 million people and generated around £128million, according to a report.
The Three Inspirational Days report examines the economic and social impact of the hosting of the opening two stages of the Tour in Yorkshire and stage three between Cambridge and London.
The Grand Depart of the 2014 Tour attracted massive crowds on the weekend of July 5 and 6 in Yorkshire as the riders went first from Leeds to Harrogate, through the Yorkshire Dales, and then from York to Sheffield via Calderdale, Huddersfield, the Holme Valley and finally Holme Moss.

It said a quarter of everyone living in the Yorkshire and the Humber region came out to watch and the Tour attracted 113,000 visitors from outside the UK, generating £33million into the UK economy.
The report said the Grand Depart generated more than £128million of economic benefit for the host areas overall, with the overall economic benefit figure expected to top £150million due to the effect of increased tourism and long term trade deals.
