The event on Saturday May 25 is part of a weekend of cycling activity that will see the Connemara area host Ireland's first sportive team time trial in Carna.
Speaking at the launch of the event, Raymond Leddy, Head of Marketing, Škoda Ireland, said: "Škoda is delighted to become the official sponsor to the Tour de Conamara. Škoda has a rich tradition in cycling and is the official partner of the Tour de France.
"To be able to get behind a local event such as this was an easy decision to make and we wish all the participants well.
"Monaghan & Sons, our local Škoda dealership in Galway, will be offering participants the option to get pre-tour VIP treatment, with further details to be announced closer to the event."
"The event has already attracted considerable international interest, with registrations already received from cyclists in the UK, France and the USA," according to event organiser Padraic Quinn.
He explained: "We are hoping to build on the success of last year's cycle and have made a number of changes to provide a weekend of activity for visitors to the area.
"The Saturday cycle in Clifden offers 140km and 80km routes. The option to take part in the Sunday team trial event in Carna is something that is already attracting a lot of attention from cycling clubs and corporate teams."
The weekend is rounded off with a Family Funathlon in Carna that will include cycling, walking and family entertainment.
The Newstalk Team Time Trial event and Family Funathlon are fundraiser events for Cancer Care West.
