For the first time in the event's 35-year history, the Silverdome stands will be empty as organisers are forced to implement major alterations.

The blue riband wheelraces have also fallen victim to the global pandemic with mass-start bunch races replacing handicap events.

All measures are designed to allow Monday's event to proceed within the indoor venue limit of 250 people with organisers hoping the outdoor George Town Carnival, to be staged two days later, will fill the void for disappointed patrons.

Launceston City Cycling Club secretary Michael Bailey said some tough decisions had been made to ensure the event went ahead.

"We're all disappointed but people have been phenomenal," he said.

"They have genuinely understood why we had to do it and the riders have been grateful that we were able to run anything. We've had some disappointed people who come each year and we cannot fit in but they were happier when they heard we had George Town in place.

"We were desperate to race for the cyclists and were trying to find a way for it to go ahead and with the help of the Silverdome staff we have done that.

"The club worked through a whole range of options to make sure we had racing and we pulled it off which we're really proud of.

"There will actually be a lot more racing than normal but to get the public in was just impossible."

The restrictions have been announced on LCCC's Facebook page, but the number of calls to Silverdome staff indicated a lot of regular patrons were still in the dark.

Renaming the carnival "the Launceston Sports Day", the post said it had "been tricky to arrange for a few reasons".

"Our COVID plan for the Silverdome only allows for 250 people in the arena," it said.

"This is going to be important for us to manage closely. We will have no general entry for the event.

"Entry will be only for life members of our club, riders, volunteers, officials and a guest of each rider. We hope to have enough tickets left for the juniors to have two guests."

The cap of 250 people includes 77 riders and their support staff, about 20 volunteers plus officials and media, all based in the centre of the track with the stands off limits.

Unlike in previous years, there will be no running or woodchopping events with the four-hour afternoon cycling-only program focused on bunch racing to avoid using holders or requiring riders to start off the track perimeter.

"The Launceston Wheel is not being run because we did not want to devalue it when riders are often up against international fields in normal years and we did not want to lose that prestige," Bailey added.

"With the George Town velodrome being outdoors, wheelraces and all the other events people would normally expect can go ahead so it should be a ripper day."

The only handicap race being run at the Silverdome will be for under-13s with parents holding riders.

In the absence of wheelraces, the scratch races will become the main events on the program with LCCC's newly-crowned national champions Josh Duffy and Lauren Perry headlining the fields.

The schedule, which runs between 1pm and 5pm, also includes points scores and keirins.

Even LCCC life members or those with Sports Carnivals Association of Tasmania passes are required to email club president Ian Loft in order to gain access.

The George Town Carnival, running between 11am and 3.30pm on Wednesday, December 30, will be a more standard event with handicaps included.

It will also include derbies, eliminations and wheelraces.
