Support During the Ride

This ride is supported by Cascade staff and volunteers, local community group volunteers, and municipal and county services.

Support and gear (SAG) vehicles are present on the route and dispatched when you call the ride support hotline. SAG vehicles can transport you and most models of bikes in the event of a mechanical or minor medical event. You should always call 911 in a life-threatening emergency.

Outriders are volunteers in white, green, and black jerseys that ride on the route, assisting you with minor mechanical and minor medical issues, like cuts and scrapes, dispensing advice and directions, and helping you to Ride S.M.A.R.T. 

Medical riders are volunteers on bike in red and blue jerseys that can assist you with minor medical issues like cuts and scrapes, dehydration, sprained joints, and other non-life threatening issues. 

Mechanics are posted at the start line and at most official rest stops.

Traffic officers are posted at highway crossings. Traffic officers will direct riders in large groups across the Longview Bridge into Oregon on Sunday only, between 8 a.m. and 2:30 p.m.

We ask that personal support vehicles please stay off of the STP route. Riders should plan to meet with personal support vehicles away from the route to prevent unsafe interactions with rider traffic.
