CARLTON fans are preparing to travel in big numbers for next week's anticipated clash against Adelaide to open Gather Round, with the Blues leading the way for supporters outside South Australia.

The undefeated Blues will help launch the feature round next Thursday night at Adelaide Oval, with the club so far identified by the AFL as having the most travelling supporters as all nine matches take place in South Australia.

The AFL announced on Tuesday it would release additional tickets for three of Gather Round's sold-out matches – including the Adelaide versus Carlton clash – on Wednesday at 12pm ACST.

Update: these additional tickets have now sold out.

Meanwhile, the AFL and South Australian Government revealed plans on Tuesday for the Pepsi Max Footy Festival, which will include a live site for fans on the banks of the River Torrens, walking distance from Adelaide Oval.  

Construction of the fan precinct in Elder Park and Pink Flat is underway and will include a 150m zip line across the river, a big screen showing all nine matches, live music and entertainment, and AFL and AFLW player appearances. 

"Irrespective of whether you have tickets for the matches or not, gather your friends and gather your family and come to this precinct because there is everything for everyone," AFL Executive General Manager Customer and Commercial Kylie Rogers said on Tuesday.

Carlton will also host a captain’s run open training session on Wednesday 12 April from 3-5pm, including kids activations and a signing session. Registrations are now open!

The home of the Double Blues will become that for the Navy Blues, with the training session to take place at Unley Oval (the ground of the Sturt Football Club), The Carlton Shop will also have a pop-up store and the bistro will be open for dinner for two sittings (5 — 6:30pm, 6:30 — 8pm): you can reserve your table here.

Some Carlton players will also be present at the Footy Festival live site on Friday from 10-11am ACST.
