Grunewald turned professional in 2010, signing a contract with Brooks Sports. In 2011, she placed third nationally in the mile run both indoors[4] and outdoors.
Grunewald was the 2014 USA Indoor 3000 m champion. She was briefly disqualified on appeal from Jordan Hasay’s coach Alberto Salazar that was based on contact Grunewald had with Hasay during the finals; however, Hasay later withdrew the appeal made on her behalf and Grunewald was reinstated as champion and awarded her World Championships berth.[6] She would finish 9th at the World Championships.
In what would be her final professional race, Grunewald ran 4:31.18 and placed 28th in 1500 m semi-final at 2017 USA Outdoor Track and Field Championships in 100-degree heat, in between chemotherapy treatments, and having had a fever just days before the race.[10]
Personal life
In 2013, Gabriele married Justin Grunewald, an internal medicine physician whom she first met while they were both students at the University of Minnesota. In 2017, Brooks released Gabe (her nickname), a 26-minute documentary film depicting her battle with cancer as well as her efforts to qualify for the 2017 World Championships.[11] Grunewald had four siblings: three brothers (Ben, Caleb, and Zach) and a sister (Abigail);[12][13] her sister was killed in a drunk-driving crash in August 2021, on her way to attending a women's soccer game in Falcon Heights, Minnesota.[14]
Illness and death
Grunewald was diagnosed with adenoid cystic carcinoma, a rare type of cancer, in 2009.[15] Due to tumors, her salivary gland was removed in 2009 and her thyroid was removed two years later.[16] She had surgery to remove a roughly five-by-six-inch cancerous tumor from her liver on August 26, 2016; a surgical oncologist performed a right hepatectomy to remove the tumor as well as the affected right lobe of her liver.[17] In 2017, Grunewald suffered a relapse, with a PET scan revealing 12 small, inoperable tumors in her liver. In 2018, she founded the organization Brave Like Gabe to fund research and raise awareness surrounding rare cancers through local races.[18]
Grunewald died in palliative care on June 11, 2019, two weeks before her 33rd birthday.[19]
