Monika Allen dressed as Wonder Woman to run the LA marathon last year, complete with a blue, star-spangled tutu.
When SELF Magazine contacted her to use the photo she was excited, but it turned out that her picture was used in a section called the "BS Meter."
The caption read in part, "A racing tutu epidemic has struck NYC's Central Park, and it's all because people think these froufrou skirts make you run faster."
Allen was going through chemotherapy for brain cancer at the time and said the outfit gave her motivation.
Today the editor in chief of SELF apologized saying, "I am personally mortified...I had no idea that Monika had been through cancer. It was an error. It was a stupid mistake. We shouldn't have run the item."
