Southern 100 organisers say they've managed to stave off a potential clash with a roadracing event in Ireland.
The Skerries 100 takes place on the first Saturday and Sunday of July - while the Southern 100 begins on Monday, July 9.
However, a number of riders say they want to compete in both events.
Race organisers in Billown say although Southern 100 newcomers have to practice on the Monday, riders who've tackled the course before can arrive on Tuesday.
