Franklin followed up a disappointing 100m freestyle on Wednesday by failing to reach the final of the 200m free.
The results mean Franklin will miss out on the Pan Pacific Swimming Championships in Tokyo next month as well as next year’s world championships in South Korea, the most important international tournaments heading into Tokyo 2020.
“I’m pretty disappointed, I definitely wanted to be better,” said Franklin, who was swimming just her fourth meet since double shoulder surgery in January 2017.
With backstroke, once one of her strengths, still causing her pain in her shoulders, she opted to swim only the two freestyle events at the championships in Irvine.
The 23-year-old finished 18th in the 200m free, clocking 1:59.56 in a field led by the 1:56.76 of Gabby Deloof.
She led the “C” consolation final through the first 150 metres before fading to finish third.
“I am learning a lot about patience throughout this,” said Franklin, her voice trembling as she acknowledged her disappointment.
“It’s tough. I’ve trained really, really hard the last seven months and was definitely hoping it would show up a little more. But it didn’t right now.”
“Long term it’s two years (until the Olympics), that’s what matters,” she said. “So that’s what we’re going to keep fighting for and I’ll just do my best until then.”
Franklin took the 2012 London Olympics by storm, winning four gold medals and following up the next year with six world titles in Barcelona in 2013.
But at the 2016 Rio Olympics she failed to make an individual final, and her lone gold from Rio came in the 4x200m free relay, in which she didn’t swim in the final.
While injuries and coaching changes contributed to Franklin’s decline, she revealed this year that post-Rio depression had also hindered her.
She chose a small stage of meetings in France and Spain last month to return to competition for the first time since Rio, and said as she competes more she’ll have to be careful not to compare herself to others on the comeback trail or to her previous self.
“I would have loved to qualify for a (national) team this summer and next summer, but now I’m just going to look at that as more time to train, more time to focus and get as good as I possibly can.”
