Event Details


Air Quality Advisory

According to AirNow (the preferred air quality authority of Napa County Public Health), wildfire smoke from the Pacific Northwest is impacting the air quality in the Northern Zone of the Bay Area, including Napa. Wildfire smoke can be extremely detrimental to cardiovascular health and to people with respiratory conditions and impacted breathing functions, like those with ALS. Currently the air quality is listed as Unhealthy for Sensitive Groups.

Air quality index

We are continuing to monitor AirNow's Fire and Smoke Map, along with reporting from the Bay Area Air Quality Management District and Napa County Public Health regarding the health and safety of outdoor activity for people living with ALS and all Napa Valley Ride and Walk participants. The current forecasts from these authorities suggest that the air quality in the vicinity of this event will remain the same between now and event day and improve as we approach Sunday, with an Unhealthy for Sensitive Groups air quality index (AQI) predicted for September 23.

While we intend to proceed with the event as planned, we advise that participants who are living with ALS, and all who will be cycling or walking, consult their physician before registering or checking in at the event site on Saturday. As the health and safety of our event participants is and will always be our number one priority, please note that we reserve the right to modify or cancel specific or all components of this event at any time, at our discretion, should conditions so require. All decisions will be informed by ongoing monitoring of the tools available to us and continued dialogue with authorities at Napa County Public Health.

For essential facts on how to interpret the index and how to protect yourself from particle pollution, please review this Air Quality Guide for Particle Pollution, developed by the U.S. Environmental Protection Agency.

On the Route

When you check-in, you will get cue sheets for the ride. The route will be marked, but you are responsible for navigating your route. Pay attention to the roads, directions, and cue sheets. Volunteer SAG support vehicles will be patrolling each route throughout the day. If you need assistance, give the standard "thumbs down" signal to indicate you need support.

If you need to contact us directly while you're on the route, an emergency hotline number will be shared as we get closer to Ride Day and will be listed on rider bibs and cue sheets.

If there is a medical emergency, call 911. If you're not sure if you should call 911...CALL 911. For other issues or concerns, please call the number on the cue sheet.

Rest Stops

Six Rest Stops are located throughout the routes. Each stop has porta-potties, water, snacks, and other goodies to help you refuel and re-energize for the next portion of your ride. Don’t forget to thank the incredible volunteers who staff each Rest Stop! The following Rest Stop and Route info is from 2022 -- it is subject to change for the 2023 ride. Check back for updates.

Please be sure to consult your cue sheet, in addition to the signage, to keep you on course.

Mechanical Support

Bike Mechanics will be set up at the Start Line area and at a few Rest Stops. Our volunteer mechanics can make simple adjustments, quick bike checks and fix flats. If your bike needs more serious work, please visit a bike shop prior to Ride Day.
