Note on the date

We understand that the 2017 Canary Challenge falls on Yom Kippur. Unfortunately, due to a combination of logistical and venue requirements, along with the necessity to avoid dates for competing events, we were extremely limited when setting a date this year. We apologize for the inconvenience this has caused a number of our participants.

Alternative Option: Friday Evening Ride

For those who still wish to support Canary but cannot participate on the day of the Challenge, we are holding a special Friday Evening Ride on Sept. 29. This invite-only event will feature an organized ride followed by wine and hors d’oeuvres at our founder’s home. This alternative was selected by the majority of respondents to a survey that included two other options. The survey was sent to past Canary Challenge participants.

Please email challenge@canarychallenge.org if you are interested in attending the Friday Evening Ride.

One of Northern California’s premier fundraising events

Each year, our amazing community of cyclists, volunteers and sponsors come together in support of cancer early detection research. Together we have raised millions of dollars to fund research programs that are improving cancer detection and survivorship. Join us!
