The amount of people visiting and spending at the TT and Festival of Motorcycling rose last year.
According to the latest survey, the two combined events brought in over 62,000 spectators, an increase of more than 2,000 compared with 2018.
Meanwhile, the combined estimated visitor spend for both came to almost £50million, meaning £35million has been contributed to the local economy.
The figures are being welcomed by Political Member for Visit Isle of Man and Motorsport, Rob Callister MHK, who says they remain grateful to everyone who supports the races along with the volunteers and organisations involved.
