The Rhinos are expected to bring their entire first-team squad to west Cumbria, including the likes of Jamie Peacock and Keith Senior, as they prepare to launch the defence of their crown, and Haven coach Ged Stokes expects a bumper attendance at the Recre.
"Leeds have a following in Cumbria anyway, and to have all their players up here gives us a great lead in to the week," he said. "It won't just be about the game, but what we can build around it, for our spectators and sponsors.
"With some of the things we are planning, everyone can share in it, not just those who turn up at the turnstiles.
"It's a chance for all the kids who don't get the opportunity to go to Super League games to see these guys in the flesh. I hope everyone takes advantage of it."
A dinner will be held the night before the match, when fans will get the chance to meet the Leeds stars.
The trip is part of a new partnership between the two clubs that has seen Kyle Amor move to Headingley Carnegie on a three and half year contract. He will be dual registered next season with both clubs but will train with the Rhinos full time each week.
