The 2010 world champion, who took to the snow for the first time this year two weeks ago, is recuperating from knee and shoulder operations in the close season.
And on his personal website he explained how he is close to full fitness, although conceded he needs to work on his consistency.
"I have trained well and the weather was fine,” Herbst, who turns 34 on Wednesday, said.
“I’m pleased with my form, but of course, after the injury break I am still a few steps off keeping up with my competitors. That was an issue but is totally normal.
“I’ve missed out on a lot of training and I have a month until the World Cup season starts to catch up.
“They key is consistency, but there is time to make up the backlog.”
The Salzburg native said that his training focus over the past two days was testing various models of skis and seeing which specifications suit him best.
“The tests only make full sense in terms of accuracy when I have reached my maximum stability, which I am working on.”
