Personal Support Vehicles

Driving directions for 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.

In an effort to ensure the well-being and enjoyment for everyone we ask all car drivers meeting riders to please use the following alternate routes to the six major food stops. The STP route is great for cyclists, not cars. Your cooperation will be greatly appreciated.

Please note that we have enough food for the 10,000 registered cyclists, Cascade volunteers, and others working the event, but not for personal support vehicle drivers.  Be courteous to those peddaling hard to make it the 200+ miles from Seattle to Portland and please purchase your own food along the route.  The mini-stops have become amazing fundraiser for local charity groups and clubs, please make use of them and support those communities.  

  1. Mile mark 24 – REI Food Stop in Kent. From the UW start line head south on Montlake Blvd to WA-520W towards I-5.  Head South on I-5 to exit 149 WA-516 E/S.  Turn Left onto Kent DesMoines Rd. for 2.9miles.  Turn left onto SR- 181 (W Valley Hwy) heading north.  Turn left onto 228th and look for REI headquarters on your left.  Please use caution when pulling into headquarters.  Watch for cyclists!
  2. Mile mark 53 – Joint Base Lewis-McChord.  Personal Support Vehicles will not be permitted onto the base only registered riders and pre-approved STP support vehicles will be admitted through our exclusive entrance.  You will be turned around at the gate, so please do not clog up traffic by attempting to enter. Please plan on meeting your rider elsewhere along the route and please make it accessible from I-5 and not the STP course.  Again this makes an unsafe riding experience for the 10,000 registered riders.  Please avoid the cycling route as much as possible.
  3. Mile mark 100 – Centralia College Mid-Point Stop in Centralia. From I-5 take exit 82 and then take a left going back under I-5. Follow Harrison Avenue when it jogs to the left and becomes W. Main Street. Go four blocks and turn right on S. Washington Ave. Go one block and the College will be on your left.  (Note: This is a food stop for the One Day Riders Only.)
  4. Mile mark 143 – Riverside Park Food Stop in Lexington. From I-5 take exit 39 and head west to SR-411 and take a right heading north on SR-411. The entrance to the park will be on your right (it is easy to miss). When leaving this location head back to I-5. DO NOT follow the riders over the Lewis and Clark Bridge.
  5. Mile mark 172 – St. Helens High School Food Stop. From I-5 after you enter Oregon and before downtown Portland take the Hwy 30 exit and head west on Hwy 30 for 29 miles to St. Helens. Take a left on Gale St. to get to the High School. When returning you will backtrack on Hwy 30 to I-5. DO NOT follow the riders' route.
  6. Mile mark 202 – Finish Line Festival at Holladay Park in northeast Portland, next to Lloyd Center. From I-5 southbound or northbound, take Exit #302-A (City Center/Rose Quarter). Follow the exit to NE Weidler St. and head east. Continue to NE 9th Ave., and take a right. Then take a left on Multnomah St. The finish line in Holladay Park will be on your right between NE 11th and 13th Ave., just south of Lloyd Center. There are many public parking lots in the area for the local businesses and some require a parking fee.
