## @slice[First 50 miles - Seattle to Spanaway](d,0,87520.05)

The STP starts with a very early am start from the University of Washington E-1 parking lot and takes you out of Seattle over the University bridge on residential streets down to Lake Washington Blvd. to Seward Park. The roads on this section are in fair condition but the views can be spectacular along Lake Washington. This is the most crowded section of the ride, so use caution and watch out for road hazards and other riders. The first mini stop is at @poi[Seward Park](2658311) just before the first climb of the day. Not steep but about ½ mile long. The route continues through Renton and Kent on flat roads. The first major stop is in Kent at the @poi[REI headquarters](2658310) with plenty of provisions to keep you going. The route follows the valley roads to Puyallup, where you have @poi[another mini stop](2658302) before you take on “The Hill” – AKA the biggest hill on the entire route. @slice[This is a 1 mile climb that averages 7% grade.](d,69535.63,71155.27) Once over the climb the route continues on flat roads into the major food stop at @poi[Spanaway Middle School](2658313).
 
## @slice[Second 50 miles – Spanaway to Centralia](d,87520.05,157782.35)

This 50 miles section is very flat on rural roads and highways. From Spanaway to Roy you will encounter a section of road that will take your full attention because the fog line has a rumble strip cut into it that makes it difficult to pass. Use caution and have a firm grip on the bars when crossing the fog line. There be some will be mini stops in Roy, @poi[McKenna](2658303), Yelm and @poi[Tenino](2658304) before you reach the mid-point at @poi[Centralia College](2658306). In Yelm you will get on a bike trail that will take you to Tenino. Make sure to use caution where the trail intersection with roads. The trail bollards have been removed but there are cones placed over the raised post holes.
[Official mid-point](http://stp.centralia.edu/) at Centralia College with 30 acres of camping space, 200+ showers, food vendors, a full cafeteria, television viewing areas (broadcasting the Tour de France for inspiration) and parking for RV and support vehicles. Additional [lodging](https://www.cascade.org/ride-major-rides-group-health-stp-about-ride/lodging) available between Centralia and Kelso including free tent camping and paid indoor options.
 
## @slice[Third 50 miles – Centralia to Lexington](d,158100.74,231207.36)

This 50-mile section seems to be the toughest with the rolling hills from Chehalis to Napavine that are very taxing on tired legs. The route uses rural one lane highways with good road surfaces. Make sure to ride single file as much as possible to allow vehicles and other riders plenty of room to pass. You will hit mini stops at @poi[Chehalis](2658305), Napavine, @poi[Castle Rock](2658308), @poi[Vader](2658307) and @poi[Winlock](3123922), site of the world’s largest egg. The major food stop is in @poi[Lexington](2658309). Get fueled up and ready to tackle the @point[crossing of the Columbia River over the Lewis and Clark Bridge](d,243205.97). For the two-day riders you will be escorted over the bridge in large groups. Don’t get distracted by the view because the bridge has some metal expansion joints that will take your full attention. Once over the bridge you are now into Oregon!
 
## @slice[Final 50 miles – Lexington to Portland](d,231158.02,326608.78)

The last 50-mile section uses the relatively flat highway 30 which is a busy road with a good shoulder. At this point of the ride you are typically pretty tired, so the lack of technical riding can be a blessing. You will have a @poi[mini stop at Goble](2658312) and then the @poi[last major stop at St. Helen’s High School](2658299) and one more @poi[mini stop in Scappoose](2658301) before you head up the @slice[last climb of the route to cross the historic St. John’s bridge](d,311550.84,312929.43). Once over the bridge the last 10 miles of the route is on residential roads before entering the high traffic areas of Northeast Portland. The finish line festival is in Holladay Park that is in the heart of Northeast Portland. Enjoy the party! You deserve it after riding 200+ miles.
