There are three types of food stops on the STP route:
- Official Rest Stops - Food is free, sports drink available, Honey Buckets onsite, full medical staffing, and mechanic onsite.
- Official Mini Stops - Food is for purchase, water may be for sale, Honey Buckets onsite, self serve First Aid kits, and some have mechanics onsite.
- Unofficial Stops - Community groups, kids with lemonade, and others set up stops along the route. Some offer free food, some offer food and drink for purchase. No additional services have been arranged at these sites. They are often unknown to the organizers until the day of the event. Riders are encouraged to use any and all stops along the STP route that fit their personal needs.
Our fully supported 200+ mile ride is kept at a comparatively low cost with five free food stops on route. Participating in mini-stops helps the communities along the route raise funds for their community work and allows us to keep your registration fee at a minimum. Food at official stops is not a three course meal; food is chosen for caloric intake and meant to keep you fueled. If you have multiple food allergies we suggest carrying bars that you know you can eat. The route goes through many small towns where grocery and convenience stores are readily available.

Rider support # (206) 841-9665
This number is printed on your bib and map. Only works during the event hours.
Official support hours
Saturday 5:00 a.m. - 9:00 p.m.
Sunday 6:00 a.m. - 7:00 p.m.
Ten support vehicles will patrol the route to pick up riders unable to continue. These vehicles will circle the course until the support hours end. While we keep an eye on the last riders and when they will finish, please be mindful that there is a point where we will end official support.
The Gold Wing Touring Association will be on route with up to 60 motorcyclists who patrol the route. They are equipped with radios and first aid kits. Gold Wings respond to mechanical problems, minor medical situations, and support traffic and crowd control in case of a detour, unforeseen hazard or emergency.
Each official rest stop and most mini-stops provides mechanical support for your bicycle. Supporting bicycle shops provide volunteer labor, but charge for parts. Come prepared to pay for bicycle repairs that you may need on the route. Many mechanics are cash only, but a few will accept credit cards. Tips for service are appreciated.
Each year up to 60 people (medics, firefighters, police officers, nurses and doctors) volunteer to ride the STP as members of the Medical Team. These volunteers are identified by red medical team jerseys or helmet covers.
Additionally, the five official food stops and the finish line will be staffed with volunteers from local Medical Reserve Corps, fire departments and more. All other mini stops on the route will have first aid supplies available for riders, but will not be staffed.
Cascade Bicycle Club Outriders are a team of trained and experienced Cascade volunteers and ride participants. They are well versed in Cascade events and are available to help with minor mechanical issues, fixing a flat and can answer any questions you may have about the ride. You’ll see them wearing the green, white and black Outrider jerseys. Flag them down if you need assistance. The safety of ride participants is their first priority.
If you are not able to keep up a pace of 10 miles/hour (including stops), you will fall behind support. Our drivers will assist you as much as possible and will often offer “bumps” to get you back into the areas of support.
If you are not coming to the start line, calculate your pace and your start time accordingly or you will be ahead of support. Do not leave the start line area after 7:30 a.m. or luggage trucks will be closed and you will be behind support services.
Our operations and support crews on STP are crucial to the success of the event, receiving phone calls and messages from the rider support line, dispatching SAG vehicles or escalating issues to first responders, and communicating with services like bike mechanics along the route.
Personal Support Vehicles (PSVs)
STP riders are well-supported with plenty of food, mechanical support, and medical support.
In past years, we have seen an excessive number of PSVs on the cycling route, leading to unsafe and unpleasant riding conditions. If you must rely on a personal support vehicle, we ask that your driver and support team follow this etiquette. Please see our Google Map with easy navigation tools to meet up points. Written directions to meet up points can be found here.
Support Vehicle Etiquette
- Avoid the cycling route at all times. Only drive the route if you are needing to pick up your rider. Cell phones work well over 90% of the route. For the other 10% riders can flag down Goldwing motorcycle support or a marked support vehicle in order to get them to a rest stop with cell phone service to call their support driver.
- Do not pull your vehicle into official rest stops. There are 5,000 riders trying to safely navigate these rest stops, and only official STP support cars are allowed to pull into these locations. Please follow the driving directions and determine meet up spots with your riders in advance.
- Do not eat the food at official rest stops. Please feel free to stop at mini-stops where community groups are selling items to raise money for their organizations. It is great to give back to them as they graciously host the ride once a year! The food at official STP rest stops are for registered riders only.
- If your rider calls for support, please have them walk to a safe place fully off the road. It is much easier to pick up a cyclist in a designated lot on the opposite side of bicycle traffic. Try not to turn directly in front of the cyclists' route whenever possible.
- Slow down, give riders three feet of space, and only pass when safe. STP is a steady stream of cyclists and that is why we ask that you stay on I-5 wherever possible.
