Not So Flatt Breast Cancer Awareness Run/Walk – 5K & 10K in Denver, CO
About the event
Join us in honoring survivors and supporting the fight against breast cancer.
The 5th Annual Not So Flatt Breast Cancer Awareness Run/Walk on October 4, 2025, will be in Westminster, CO. Participate in our 5K or 10K event supporting breast cancer research.
Honor, remember, and support the fight against breast cancer at our annual breast cancer awareness run. In 2021, my father lost his battle with breast cancer, and we started this event to bring the community together, celebrate survivors, and support those still fighting. His last name was Flatt—but his fight wasn’t flat, and neither is the strength of our community.
Event Highlights:
Race Options: 5K walk/run and 10K run—perfect for all ages and fitness levels.
T-Shirts & Medals: All participants receive a race T-shirt; top finishers earn medals.
Special Registration Offers:
5K: $30 until September 12th, then $35. Donate $35 while registering and get $30 off!

Race Day Goodies: Bib pickup includes your race day schedule, shirt, and surprise goodies. Sign up after September 15th and your shirt size may not be guaranteed.
Virtual Run: If you’re unable to attend in person, you can register for our virtual run! The signup cost goes straight to donations for Breast Cancer Research. Submit your photo, and we’ll feature it on our website and social media to celebrate your participation.
Why Participate:
Support groundbreaking breast cancer research through the Breast Cancer Research Foundation.
Join a compassionate and inspiring community affected by breast cancer.
Honor loved ones and survivors while enjoying a fun, family-friendly event.
