This summer, the beautiful city of Denver will be the first stop in the Susan G. Komen 3-Day® series, and we want YOU to be a part of it. When you arrive on Aug. 1, you’ll be immersed in the Pink Bubble, a vibrant community well known for its spirit of hope, remembrance and celebration.
The 3-Day is an up to 60-mile journey where participants walk for themselves, for loved ones or for people they may not know but whose experience with breast cancer they want to honor.
While Denver can see temperatures in the summer reach the 90s, Nancy Partridge, a breast cancer survivor and advocacy ambassador for the Komen Center for Public Policy, says the Mile High City is the perfect backdrop for the 3-Day’s memorable experience.
“In Boulder it’s a real treat. It’s a quaint, quirky, little college town that is set up against the Flatirons, which is some of the most beautiful mountains that you will see up close and personal,” Nancy, who lived in the city for 20 years, explained. “Denver is shaded by high rises, and in Boulder, most of the route is shaded by trees. So, when you feel the sunshine on your face, it feels good.”

However, with Denver’s high altitude (5,280 feet above sea level), Nancy emphasized the importance of being prepared. “It’s important for walkers to stay hydrated. Drink plenty of water, avoid alcohol and eat foods high in potassium like avocado and cantaloupe.”
The Denver 3-Day isn’t just about the walk; it’s also about the impact. In 2024, 700 walkers and 220 crew members gathered in Denver and raised $2.3 million to support breast cancer research, education, advocacy and patient support services. Tracey Bahlo has participated in the 3-Day more than 20 times to honor her sister, a two-time breast cancer survivor, as well as others touched by breast cancer. She says it’s an incredible experience.
“It raises money for meaningful research and support, and provides hope,” Tracey said. “Every year at the San Diego 3-Day, there’s a woman with a sign that reads, ‘People like you saved me.’ That’s why I walk.”
Whether you’re a Colorado native or visiting for the first time, the 3-Day offers a new perspective on Denver. The route highlights some of the city’s most scenic spots—from Boulder’s hilly streets to iconic landmarks like Coors Field and the famous 40-foot blue bear at the convention center.

With warm weather likely in August, Tracey recommends some tips to stay cool: “Start walking early and wear a long sleeve, light weight shirt. The sun on your skin will be hotter. And don’t forget to wear an ice wrap around your neck!”
Since it began in 2003, the 3-Day series has welcomed more than 500,000 participants and raised more $915 million. Don’t miss your chance to be a part of this amazing journey. Visit the 3-Day today to register for Denver!
