About the Not So Flatt Breast Cancer Awareness Run/Walk - 5K & 10K
The name tells you something true: Westminster has hills, and this course finds them. The race is built around breast cancer awareness, started after the organizer lost his father to the disease. His last name gave the event its name. There are several distance options, and the route is not the kind you coast through.
Bib pickup happens on race morning. Surprise goodies come with your bib. The event benefits the Breast Cancer Research Foundation, and there is a virtual option for those who cannot make it in person.

The Not So Flatt Breast Cancer Awareness Run/Walk - 5K & 10K has been held every year since at least 2021. That is as far back as RunSignup's records for this race go, so it may well be older.
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Nov 12, 2026.
