About the race

Pinkathon Challenge for Breast Cancer offers virtual and in-person options in October. The in-person event is anchored at the San Francisco Ferry Building, starting near Gott’s Roadside, with participants running, walking, or cycling any distance. Distances include 5K, 10K, 10M, 13.1M, 26.2M, 50K, plus the Pink Ribbon Trail and a choose-your-own option.

It’s marketed as a Free, Unsanctioned Fat‑Ass Run/Walk—no official times, no aid stations, and no trail markings—supported by maps, turn-by-turn directions, gear storage, and a vibrant community atmosphere. The event welcomes participants of all ages and abilities in a supportive, pink-themed environment, with online donations benefiting the Breast Cancer Research Foundation.
