  • Total distance: just over 206 miles
  • Maximum altitude: 463 feet
  • Total ride elevation gain: 5,024 feet

Food stops

There is potable water at the start line, but no food. Eat before you arrive so you're fueled and ready to ride.

Food along the course is chosen for its nutritional quality, carbohydrate and potassium replacement, taste and quantity. The ride food is not meant to be a meal but food that will keep you going without filling you up. If you have special food needs, please plan accordingly. Food stops also provide water, portable toilets, mechanical assistance and first aid.

New this year, Wilcox Family Farms will be onsite at the McKenna Elementary School mini-stop distributing free samples of their 100% organic and cage free hard boiled eggs.  Wilcox Farms is a 4th generation family business that continues the tradition of sustainable farming by providing the Northwest with quality, local egg products.

Mini-Stops and Services

Mini-stops are located approximately halfway between each food stop and feature food for purchase. Mini-stops are staffed and sponsored by local community organizations that use them as fundraisers. They offer mechanical support, portable toilets and first aid kits (no OTC drugs and no medical staff) and are not associated with Cascade Bicycle Club. Below is an approximate list of the mini-stops and the groups involved. 

Route Support

Ten thousand bicyclists ride STP every year; almost all finish. Group Health STP Presented by Alaska Airlines provides mechanical support, food, first aid, water and toilets every 20 miles. Personal support vehicles (PSV) are strongly discouraged because they create additional hazards for the cyclists, as well as local traffic.

If you insist on riding STP without personal support, please make sure your PSV driver knows to follow the instructions for personal support vehicles. Personal support is not allowed to follow the cycling route and by registering for the STP you have signed and agreed to comply with the ride rules set by the organizers.  You are endangering riders and heavily effecting the small communities we ride through.  Please be respectful of the other 9,999 riders who want to enjoy a low traffic ride.  


Our volunteer support team is the best in the business.  Twelve support vehicles will patrol the route to pick up riders unable to continue. These vehicles will circle the course until the last rider finishes each day. The support vehicles will shuttle stranded riders to the nearest point where services are available. The support vehicles are not personal "taxis". If you are not able to continue due to mechanical or physical reasons, you will need to make your own arrangements for transportation to your final destination. The support pickup service requires patience and has limited capacity; you may have to wait some time before you're picked up.


Each major food stop and mini-stop provides mechanical support for your bicycle. Supporting bicycle shops provide free labor but charge for parts. Come prepared to pay for bicycle repairs that you may need on the route. Many bike shop mechanics will take MasterCard/VISA as well as cash or check. See a full list of shops providing mechanical support on the STP.

Blow a tube?

At STP, donate your bike tube to Alchemy Goods. That’s one less tube for the landfills. And one more upcycled messenger bag for someone who cares as much about our world as you do. Look for Ag donation points along this year’s STP route.





The Cascade Bicycle Club Outriders are a team of well-trained and experienced Cascade Bicycle Club volunteers and ride participants.  They are well versed in CBC events and are available to help with minor mechanical issues, help you fix your flat, and answer any questions you may have about the route, food stops, or cycling in general.  They are wearing the white and black OUTRIDER jerseys.  Feel free to flag them down if you have any questions or need assistance in any way. They are ambassadors of good cycling etiquette and safe riding.  They may remind you that single file is safer or warn you of upcoming hazards on route.  Please understand they are there to keep everyone safe on the road to Portland.  Your riding habits effect others and it is not fair to cut someone elses trip short when most accidents can be prevented with safe riding skills. Feeling overwhelmed by group riding?  Want to know how many miles to the next rest stop? They are there to help!


Each year up to 100 cyclists (ski patrol, medics, firefighters, police officers, nurses and doctors) volunteer to ride Group Health STP Presented by Alaska Airlines as members of the Safety and Medical Team. These volunteers are identified by red safety jerseys, vests or helmet covers. The Safety and Medical Team will ask riders to refrain from unsafe or discourteous riding practices. This year, many support riders will be Group Health volunteers, like 8-time STP veteran and Group Health physician, Steven Bock.


The 5 major STP food stops and the finish line will be staffed with medical volunteers provided by Cascade Bicycle Club. All the other mini stops on the route will have first aid supplies available for riders, but will not be staffed. If you have a medical issue on route that needs immediate attention, please flag down one of the Goldwing Support motorcycles or one of the official STP Support cars.


The Gold Wing Touring Association (GWTA) will be on route with up to 100 motorcyclists who patrol the route equipped with radios and first aid kits. GWTA responds to mechanical problems and minor medical situations. They can radio for help in situations requiring medical assistance or rider transport. If you need assistance, give the "thumbs down" signal to a GWTA motorcyclist. To signal your appreciation, give the "thumbs up" sign.
