There are a number of alternatives for next year, I guess its up to the individuals going to races to discuss, in previous years we've had a similar thread, opinions have been canvassed and a collective has seemed to form around one race.
As for choosing the Pirate Championship, we've tried to find races that will appeal and we've not done before and are top class events:
In previous years we've done:
2005 - IM Swizerland
2006 - IM Germany
2007 - IM Austria
2008 - IM France
2009 - IM Switzerland
2010 - Challenge Roth
2012 - IM Regensburg
2013 - Outlaw
In addition smaller groups / individuals have done many other races
There is a new Ironman this year (IM Sweden), which could be a prospect for the Pirate Championships 2013, as could Challenge Henley which ive seen suggested. Its also likely that Outlaw and Wales will be popular with some this year.
The other contender and a personal favorite of mine is Lanza but understandably it doesnt appeal to everyone due to cost and its reputation.
One question ive personally been battling with is whether Lanza is never deemed worthy of the Pirate Championship location due to its difficultly, cost? In previous years we're gone with the majority decision or race with the highest participation.
