A SCAR (self contained adventure racing) event.  Cruise around the Hollyford-Big Bay-Pyke circuit utilizing a packraft. Take photos at select locations en-route to prove that you've been there.  Carry everything with you from start to finish.  It is good to have goals, and the goal is under 24 hours.  Good luck.  Will be a smidge harder this year because of the flood. And will also involve a bit of mountain biking. Hoo ra!
