She qualified for two swimming events by attaining B-standard entry times of 26.34 (50 m freestyle) and 56.74 (100 m freestyle).

In the 100 m freestyle, she was reassigned in heat three against seven other swimmers, including Hong Kong's Hannah Wilson and Bahamas' Arianna Vanderpool-Wallace. She touched out Cyprus' Anna Stylianou to take the fifth spot and thirty-fifth overall by three hundredths of a second (0.03), in a time of 56.35 seconds. In the 50 m freestyle, Ragnheiður finished fourth in heat eight by 0.13 of a second behind Jamaica's Natasha Moodie, clocking at 25.82.

Ragnheiður did not compete at the 2012 Summer Olympics in London as she was pregnant with her son.

She took an eight-week "Acting for Film" course with New York Film Academy in Los Angeles, which she "loved", and then enrolled for a one-year programme. She graduated in 2015. It was also announced in the 2020 Game Awards that she would star in an animated series based on the popular Studio Wildcard game Ark: Survival Evolved in 2022 playing the role of Queen Sigrid.
