While we haven't released the exact route for 2018, we expect few changes from 2017.  We've provided last year's route information, for planning purposes, below.

2017 Route Map

This is the finalized 2017 route.  You can use this link along with your official route map.  Printed maps with additonal information will be included with your packet.  Turns will also be marked in chalk with the official STP stencil. 

What has changed in 2017?

  • Due to a shortage of JBLM staff in 2016 we will not have access to the ASP road on Joint Base Lewis-McChord.  We are back on Pacific Hwy and 507 to Roy.  This is the original route from 2014 or earlier.  There are two sets of railroad tracks on this stretch of 507 that riders should be aware of, they will be covered by mats and riders should ride single file for the entire stretch between Spanaway and Roy.
  • Yelm mini-stop is back at Yelm City Park, just before entering the Yelm-Tenino trail.  Clif Bar will be moving their sampling set up to Yelm. 
  • There is a major repaving project just north of Winlock.  Riders will reroute to Tennessee Rd and reconnect with Hwy 603 in Winlock.  The Winlock Mini-stop will move to Winlock Elementary School in order to remain on route. 
  • If you are going to track your ride, we recommend you to download Bike Computer, the official cycling app of STP 2017. Available on Android and iPhone, with the app you can track your performance, navigate and find fellow cyclists on a map, and share your rides with the cycling community on Strava and Facebook. Bike Computer includes a safety feature that can protect you in a case of an accident.  Learn more at

Food stops

There is lmited water at the start line fill up before you arrive, but there will be water on hand as well.  There is no food at the start line.  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 and have a few bars or snacks that you KNOW you can eat. Food stops also provide water, portable toilets, mechanical and medical assistance.  

We ran a test program of gluten free salads last year and they flew off the shelf!  We have doubled the number available and hope you like them!

Featured food:

Spanaway- Gluten free Southwest Chicken Salad
Lexington- Gluten free potato, chickpea, and kale pesto salad (cold)
St. Helens- Gluten free chef's salad, mixed hard greens and veggies, hard boiled egg, tomato, cheese, olives, (with turkey optional)

Wilcox Family Farms will once again 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 fourth generation family business that continues the tradition of sustainable farming by providing the Northwest with quality, local egg products.

Clif will  be onsite at the new restop in Yelm to provide free bars and samples of other products to riders.

2017 Food Stops

​Personal Support Vehicles (PSVs)

STP riders are well-supported with plenty of food and mechanical support and DO NOT NEED A PSV. Despite this fact, we continue to see an excessive number of PSVs on the cycling route, leading to unsafe and unpleasant riding conditions.  Want to take the guessing out of supporting your rider on the road?  BAT (Beacon Athletic Tracking) can help!  Check out their personal GPS tracking devices.

Support Vehicle Etiquette 

  1. 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.
  2. Do not pull your vehicle into official rest stops.  There are 10,000 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. 
  3. 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, so please leave that food for them.  
  4. 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 right in front of the cyclist's route whenever possible.
  5. Give riders three feet 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 and you do not follow the cycling route.

Please see our Ride With GPS route for drivers with suggested meet up points.  Written directions to meet up points can be found here.
