Pinkathon 2025 Virtual and In-Person Challenge for Breast Cancer!

Please join us for the 2025 Pinkathon Challenge for Breast Cancer!  Run/walk virtually anytime!  The in-person event will take place on Sat. October 25, 2025 in San Francisco!  If you decide to run virtually,  you can run, walk or cycle - any distance you want - anywhere you want - even if you're in another state, another country, or another planet!  You may complete your distance any time and across as many days as you want, any time before October 31, 2025.  Last year, we raised nearly $50,000 for our charity, the Breast Cancer Research Foundation! Let's do it again!

Registration for the 2025 Virtual Pinkathon will open on 5/1/25!  You can choose any distance, and complete your challenge anywhere, anytime before the end of October 2025!

The Pinkathon San Francisco In-Person Event will take place on Saturday, October 25, 2025, at the San Francisco Ferry Building by Gott's Roadside Outdoor Patio and Joyride Pizza at Pier One. 

This event is always a FUNDRAISER for the Breast Cancer Research Foundation.  Donations will remain open until November 30, 2025!  Donate at https://pinkathon.com/donate

The In-Person Pinkathon San Francisco is a "do-it-yourself" or "fat-ass" event, meaning that we have NO AID STATIONS and NO COURSE MARKINGS (except for the 5K & 10K turnarounds & Pink Ribbon Trail).  You must bring/carry your own water and snacks.  We have downloadable maps and turn-by-turn directions that you can find at https://pinkathon.org/pinkathon-maps

Registering for the Pinkathon In-Person Event at the San Francisco Ferry Building on Sat. Oct. 25, 2025 is $25.  Your $25 registration fee is NOT tax-deductible.

Registering for the VIRTUAL Pinkathon is FREE.  Registration for the In-Person Pinkathon is $25 to cover basic setup costs.  Our goal of raising $50,000 this year for BCRF is not possible without your additional VOLUNTARY DONATIONS which go directly to the Breast Cancer Research Foundation! https://pinkathon.com/donate

Whether you register for the Virtual or In-Person Pinkathon Event, we DO expect EVERY participant to ALSO make a voluntary TAX-DEDUCTIBLE donation to our charity, the Breast Cancer Research Foundation, the top-rated breast cancer charity in the world!  Make your tax-deductible donation to BCRF during registration or at https://pinkathon.com/donate. You can also create your own individual or team/group fundraising page and raise donations from your family, friends and co-workers! 

To keep our fees super-low, your in-person registration fee of $25 does NOT include things like free T-Shirts, but we will have some refreshments, water and snacks at the start/finish and SWAG/prizes for those who make donations to BCRF (we do keep track!). 

If you want to buy a neon-pink 100% polyester Pinkathon Performance T-Shirt, you need to order and pay for it online at least 3 weeks in advance at the "T-shirts" link on the left side bar. The shirts will be sent to your home.  NO T-shirts will be available for sale at the Start/Finish.

VOLUNTEER!  Up to 50 volunteers are needed on Sat. 10/25/25 at the SF Ferry Building.  Volunteers will receive free pink cotton t-shirts with the Pinkathon logo and sponsor logos. Volunteer free now at https://pinkathon.com/volunteer
