If there's no information on the website, then it may be that no-one knows yet! This is the first year that they've run it and I suspect they will want to see how it goes before starting to think about next year.
There's a thread about the race on the TriTalk forums (which includes contributions from the race organiser) - if you have a look at the start of it then you'll get some idea about how entries went this year.
(I've been following the TriTalk thread, because I know that part of the world a bit, and my boyfriend and I thought about getting involved with support/crewing until we realised that it is the same weekend as his big race of the year!)
