"I have a lot of bumps and bruises. My hip is really sore and while I've had lots of treatment it is just too sore to compete. Also, my bike is damaged and I can't ride it and we don't have another one in this country."
Bozzone said he was greatly looking forward to the race.
"The race meant so much to me. I was actually out riding the northern part of the course in Albany on the same roads where I had my very first duathlon race.
"I could have tried to start but honestly I would not have got far, and I would stand the danger of doing something more serious that would affect my chances with Ironman New Zealand which is only seven weeks away."
The race offers a prize purse of $90,000 for the professionals, as well as 50 qualifying spots for the Ironman 70.3 World Championships in Las Vegas and 30 spots for the Ironman World Championships in Hawaii.
The rest of the field are all in place and have until 5pm to place their bikes in transition ahead of the race, which starts at 6.30am tomorrow. The winner is expected by 10.15am and the final participant by 3pm.
