Vienna, Virginia — John Brenkus, who gained fame as the co-creator and host of the innovative television program “Sport Science,” has died at the age of 53. The Virginia Department of Health Office of the Chief Medical Examiner confirmed that Brenkus’s death on May 31, 2025, was a suicide following a long struggle with depression.
A statement released on June 1 through Brenkus’s social media profiles and the Brinx.TV website, a platform he later founded, disclosed his battle with depression. The message also expressed the deep sorrow of his family and close friends and emphasized the importance of seeking help for anyone struggling with similar issues.
Brenkus, born in Vienna, Virginia, in July 1971, was best known for “Sport Science,” a show that debuted on Fox Sports Network in 2007 and later moved to ESPN. The series, which ran until 2017, won six Emmy Awards for its unique approach to debunking myths in sports by applying scientific principles and advanced technology. Brenkus not only hosted the show but also actively participated in the experiments, often testing athletic feats against professional sportspeople.
Apart from his work on television, Brenkus was an entrepreneur, author, and athlete. He co-founded Base Productions and penned “The Perfection Point,” a New York Times bestseller that explores the extremes of human athletic capabilities. Additionally, Brenkus was deeply involved in endurance sports, including participating in several Ironman Triathlon races.
In January 2023, Brenkus shared his personal challenges with mental health during an appearance on former NFL player Marcellus Wiley’s show “Never Shut Up.” He opened up about his descent into depression following significant life changes, including the sale of “Sport Science” and relocating to Park City, Utah. Brenkus attributed his mental health decline to factors such as isolation and physical injuries.
A particularly poignant moment from Brenkus’s discussions on mental health included a story about his rescue dog, Zeppelin. During a critical moment of despair, Zeppelin intervened, pulling at Brenkus’s clothing, which diverted his suicidal thoughts and prompted him to reach out for help. Post this episode, Brenkus emphasized the effectiveness of the treatment he received from a Virginia-based psychologist, which he described as a turning point in his battle with depression.
Colleagues from ESPN and other figures in sports media expressed their grief and paid tributes following Brenkus’s death. Randy Scott from ESPN remembered him as a brilliant mind who had a unique capability to merge the worlds of science and sports, bringing complex ideas into the living rooms of everyday Americans. Matthew Berry, former ESPN fantasy football analyst, praised him for his kindness and creativity.
Brenkus’s legacy, as noted by his colleagues and friends, extended beyond his television achievements. He was regarded as an innovator and an advocate for mental health awareness, often discussing the complexities of depression and the importance of seeking help.
Following the announcement of his death, tributes poured in, including from Wiley who re-shared the announcement with heartfelt messages. As the community mourns the loss of Brenkus, his openness about his mental health struggles remains a vital part of his enduring impact.
In light of Brenkus’s death, several news outlets have included information on mental health resources, reminding the public that help is available through the Suicide and Crisis Lifeline by calling or texting 988, and for international support, resources are provided by the International Association for Suicide Prevention.
