According to the 2008 B2B website:
When will registration open for the 2009 event? General registration will open on December 1, 2008 at 8AM for the 2009 event. The 2009 event date is set for Saturday November 7, 2009.
In 2008 the registration fee was $250 for USAT members for the iron distance triathlon. Refunds minus $50 were available up until August 1, 2008 or until the event filled, whichever came first.
CAVEAT! There may be NO refunds if the event fills, which it may do very soon after registration opens. Check the current policy carefully.
