The year the locals took their race back. The handicap system was again used which saw two Penrith teenagers and training buddies, Adrian Comminotto and Brittany Orr, fight it out for the outright honours.
Adrian managed to catch Brittany with 500 metres to go as Brittany had minimal running training from an injury. Adrian improved from his 5th place the previous year while Brittany moved up from her 3rd placing in 2004.
This year also saw the Nepean legends drop to only 4. The Nepean Legends are those that have competed and completed every Nepean Triathlon since the beginning in 1982. These are now Greg Chapman, Eugene Irvin, Peter Smith and Greg Davies.
