The harrowing story that surrounds colorectal cancer in men under fifty who live healthy and active lives

Press Release // TETON GRAVITY RESEARCH (TGR), BEST KNOWN AS THE GLOBAL LEADER IN ACTION AND ADVENTURE SPORTS MEDIA, has tackled something far larger than a steep ski line in their recent documentary, Mountain in the Hallway. The film explores the stark realities that surround colorectal cancer.

The documentary is told through the lens of two fathers battling colorectal cancer connected by their struggle, their desire to live fulfilling mountain lives, and the sacred landscape of the Grand Teton. After being diagnosed with colorectal cancer, both Tate Macdowell and Brian McDonnell underwent chemotherapy, surgery, and spent large swaths of time wandering the halls of their respective hospitals. In their wandering and waiting for the nausea to pass, they both found themselves entranced by the dramatic relief and exposure of the highest point in the Grand Teton National Park. The Grand Teton, looming 13,775 feet over Jackson Hole, is the mountain in the hallway.

Through social media and mutual friends, Tate and Brian became compadres as they fought through chemotherapy and multiple surgeries. Ultimately, the mountain in the hallway became a common goal that offered strength, peace and motivation. Tate and Brian decided to meet in-person and attempt to climb the Grand Teton together. With the generous support and sponsorship from Black Diamond Equipment, Teton Gravity Research and Exum Guides, both men gathered in the shadows of the Tetons to celebrate the mountain, their families, friends and life.

What is colorectal cancer? Colorectal cancer is a disease characterized by the unchecked division and survival of abnormal cells in the colon or rectum. In the United States, colorectal cancer is responsible for the second most cancer deaths, and the key to surviving and beating colorectal cancer is early detection. According to the American Cancer Society, “colorectal cancer is much more common in older men than in younger patients.” Mountain in the Hallway tells the stark reality that younger men who live healthy and active lives are increasingly at risk of developing tumors in their large intestine and that the US healthcare system needs to adjust the guidelines for preventative screening that is covered by health insurance for adults younger than forty years old.

In 2017 in the US, an estimated 135,430 people will be diagnosed with colorectal cancer and about 50,260 people will die from the disease. Colorectal cancer is the third most commonly diagnosed cancer in both men and women. Approximately 4.6% of men (1 in 22) and 4.2% of women (1 in 24) will be diagnosed with colorectal cancer in their lifetime.

Teton Gravity Research hopes that this film will educate, shape the future of the preventative healthcare system and remind you to love the ones you’re with.
