He caught a stomach bug and faded at the Ironman 70.3 World Championships in Las Vegas and withdrew on the run in his debut at the Ironman World Championship in Hawaii, when he was unable to keep down any nutrition.
"It certainly wasn't the finish to the season that I had planned," Docherty said. "I was in terrific shape but this endurance stuff, particularly Ironman is new to me. I said when I took it up that it is swim, bike and run but there's a fourth discipline and that is nutrition.
"In Olympic distance racing you just bolt on a drink bottle and that's it. It is part of the learning process and I come into the second year of Ironman racing much wiser and better prepared."
Bozzone, beset by an Achilles injury in 2012, then had his progress stalled by the freak accident before January's inaugural Auckland race.
He rediscovered his mojo in the second half of the season, reeling off three wins in Florida, Mandurah and Shepparton and was never off the podium, highlighted with the outstanding second in Las Vegas.
"You always want more, of course, but to come from the dark place I was in and have such success is rewarding." Bozzone said.
"It really hurt to miss this chance to compete in such a big race in my home city. So I think I will be doing my bike training on an indoor trainer until the race."
The professional field is finalised at the end of the month.
