However, she admitted afterwards that the injuries continue to hamper her, and with the World Championships less than a month away revealed she will not go to the event if not fully fit.
"It's pain. It's one little bit that's really painful. When I compress it and when I'm pushing off it, it hurts," Ennis-Hill said.
"If I had one event to prepare for then maybe it would have been a bit easier, but having to train for seven events and get all the work done that I needed to get done, it just hasn't happened unfortunately. I want to be competitive, I don't want to go to just enjoy it. I want to contend for the gold medal."
Despite the worries, Ennis-Hill was glad to get her campaign underway, even at this late stage of the year.
"I am happy to be back, it's been a while," she said. "It's been really frustrating. I didn't think I'd be opening up my season in July, and practically the end of July."
