Perri Shakes-Drayton has revealed she is fully fit for this weekend's Aviva Birmingham Grand Prix after an injury derailed her Olympic medal hopes earlier this month.
The 23-year-old missed out on a place in the 400 metre hurdles final after she finished third in her semi-final heat but confirmed the hamstring problem she suffered at the Games is behind her, albeit still something of a mystery.
"During the warm-up prior to my Olympic semi-final I felt my hamstring tighten up," Shakes-Drayton said. "I tried my best to make it feel better but in my mind I knew it didn't feel right.
"The opportunity of being at the Olympics, I'm not going to pull out. I was hoping I was going to pull though."
Shakes-Drayton added: "Me and my coach are looking to meet up and discuss it because we don't want this kind of problem to happen again.
"Maybe it will be something that needs to be dealt with before winter training starts."
However, the London-born athlete is hoping to finish with a strong result in the UK's final Samsung Diamond League meet of the year this weekend and replicate her personal best of 53.78 seconds at Crystal Palace last month.
"I'm hoping to end on a high. That's my aim," she said. "I'm going to go out there and try to win but these girls are top girls and I'm just hoping to go out there and do my thing and repeat what I did in Crystal Palace.
"I feel 100% fit. I feel good. With my event you can't really judge what's going to happen so I've just got to go out there and try and stay in contention."
