The intersection of personal tragedy, physical endurance, and philanthropic dedication often produces stories of profound human resilience, but few are as illustrative as the journey of James and Elizabeth Gunnett. Their story, which began on the rugged trails of the Pacific Crest Trail (PCT) in 2018, has evolved from a quest for personal healing into a lifelong commitment to the fight against pediatric cancer. As the Ultimate Hike program prepares for its latest iteration in the majestic landscapes of Mt. Tamalpais, the Gunnetts’ narrative serves as a testament to the community-building power of CureSearch for Children’s Cancer, an organization that has raised more than $10 million to fund clinical research and innovative treatments.
The Genesis of a Shared Mission
The year 2018 marked a pivotal turning point for both James and Elizabeth Gunnett, though they were then strangers navigating separate paths of hardship. James Gunnett was grappling with a period of significant personal loss, seeking a way to channel his grief into a constructive outlet. He was introduced to the Ultimate Hike by Chris Morton, a coworker and a veteran coach for the program. Morton’s involvement was deeply personal; his daughter, Violet, is a survivor of liver cancer, and his dedication to the cause was born from the direct experience of a family battling the disease.
Simultaneously, Elizabeth was contending with severe clinical depression and was searching for a rigorous physical challenge that could provide both a sense of purpose and a supportive social environment. Upon attending a CureSearch information session, she found herself drawn to the organization’s dual focus on high-stakes physical endurance and the urgent need for pediatric cancer research. The Ultimate Hike is not a traditional charity walk; it is a grueling endurance event that requires participants to trek between 20 and 30 miles in a single day, necessitating months of training and a significant fundraising commitment.
Overcoming Adversity on the Trail
The 2018 hike was not without its logistical hurdles. Shortly before the event was scheduled to commence, Elizabeth faced a setback when her hiking boots were stolen. In the world of long-distance trekking, where footwear is meticulously broken in to prevent injury, such a loss could have been disqualifying. However, embodying the resilience that the event seeks to honor in cancer patients, she persevered. It was during this inaugural challenge that James and Elizabeth met, finding a shared resonance in their motivations and their dedication to the cause.
The connection forged on the trail deepened over the subsequent two years. The symbolic weight of the hike remained central to their relationship, culminating in 2020 when James proposed to Elizabeth at Big Bear Lake, California. The proposal took place on the very trail where they had first connected, linking their personal future to the mission that brought them together. On October 11, 2021, the couple married, and they have since completed six Ultimate Hikes as a duo. Today, they lead "Bear Snacks," a Northern California-based hiking team dedicated to fundraising and recruitment for CureSearch.
The Landscape of Childhood Cancer in the United States
The Gunnetts’ dedication is fueled by the sobering statistics surrounding pediatric oncology. According to data provided by CureSearch and various national health institutes, approximately 42 children are diagnosed with cancer every day in the United States. While survival rates for some forms of childhood cancer have improved significantly over the last several decades, cancer remains the leading cause of death by disease for children in the U.S.
The "survival gap" remains a critical concern for medical professionals and advocates. Many survivors of childhood cancer face lifelong health complications—often referred to as "late effects"—resulting from the toxic nature of treatments like high-dose chemotherapy and radiation, which were often originally designed for adult physiology. CureSearch directs its funding toward research that specifically targets high-risk cancers with low survival rates and seeks to develop "smarter" treatments that are less toxic to developing bodies. To date, the Ultimate Hike program has been a primary driver of these efforts, mobilizing thousands of hikers to raise the capital necessary for Phase I and Phase II clinical trials.
A New Chapter: The Transition to Mt. Tamalpais
As the program looks toward the future, the California Ultimate Hike is undergoing a significant geographic transition. For the upcoming season, the event will move from its traditional routes to the iconic terrain of Mt. Tamalpais in Marin County. This shift offers a new set of challenges and aesthetic rewards for participants.
Mt. Tamalpais, rising to an elevation of 2,571 feet, provides a diverse ecological backdrop for the hike. Participants will navigate through enchanting oak woodlands and serpentine grasslands, with the trail offering panoramic views of the Farallon Islands, the hills of the East Bay, and the San Francisco skyline. The planned route covers up to 19 miles of strenuous terrain. While the distance is slightly shorter than some previous 30-mile iterations, the elevation gain and technical nature of the Marin County trails ensure that the event remains a true endurance test.
The move to Mt. Tamalpais is strategically designed to broaden the event’s reach within the Northern California community. By bringing the hike to a location with high visibility and a robust local hiking culture, CureSearch aims to attract new participants who can contribute to the $10 million-plus total already raised by the program nationally.
The Psychology of Endurance and Philanthropy
The success of the Ultimate Hike can be analyzed through the lens of "adventure philanthropy," a growing trend where donors engage in extreme physical feats to mirror the struggle of those they are helping. For participants like the Gunnetts, the physical exhaustion of a 20-mile hike serves as a visceral reminder of the stamina required by children undergoing cancer treatment.
"The PCT hike was life-changing," Elizabeth Gunnett noted, reflecting on the psychological impact of the event. "But it’s the incredible people we meet each year—those who pour their hearts into this cause—that keeps us coming back." This sentiment highlights the "community of care" that CureSearch has successfully cultivated. By connecting bereaved parents, survivors, and those simply seeking a challenge, the organization creates a support network that extends far beyond the trail.
Financial Impact and Research Milestones
The funds raised by teams like "Bear Snacks" are critical because pediatric cancer research is historically underfunded compared to adult cancers. It is estimated that only about 4% of the National Cancer Institute’s (NCI) federal budget is dedicated specifically to childhood cancer. This leaves a significant gap that must be filled by private organizations.
CureSearch utilizes a unique "accelerator" model, which prioritizes funding for research that has a high probability of reaching clinical trials within a short timeframe. This approach is intended to bypass the "valley of death" in drug development, where promising laboratory research fails to reach patients due to a lack of funding for human trials. The $10 million raised by the Ultimate Hike program has contributed to several breakthroughs in immunotherapy and targeted molecular therapies, offering hope to families who have exhausted standard-of-care options.
How to Contribute to the Mission
As the Gunnetts approach their fourth wedding anniversary and their seventh year with the program, their focus remains on expansion. They continue to advocate for both hikers and "virtual" supporters. The "Bear Snacks" team is currently active and seeking new members for the Mt. Tamalpais event. For those unable to commit to the physical rigors of the hike, CureSearch provides platforms for direct donations, which contribute to the same research goals.
James Gunnett emphasized the longevity of their commitment: "Everywhere we go, we share our story, hoping to inspire others to join us on this life-changing journey. We continue to find joy in hiking and fundraising for CureSearch."
The Ultimate Hike stands as the only national endurance hiking program dedicated to childhood cancer. Its continued growth suggests a robust appetite for philanthropic efforts that combine physical challenge with high-impact medical advocacy. As the program moves into the forests of Marin County, it carries with it the stories of thousands of children, and the enduring partnership of two hikers who found love while fighting for a cure.

The trail ahead remains long, but as the Gunnetts have demonstrated, it is a journey defined by hope, resilience, and the collective power of a dedicated community.
