Here's the thing about Tia-Claire Toomey, she hadn't been doing CrossFit for a long time when she made it to her first games in 2015. Her background was in track and field but she represented her country at the Olympic Games in Rio in the 58 kg category in weightlifting. That's 2016.
The same year as she competed in her second CrossFit Games. She was 2nd on the podium. She has been number one ever since.
