The Spring 400k starts and ends at the Redmond Inn, in Redmond, WA. Due to local road construction, you’ll briefly head south on the East Lake Sammamish Trail, then the route gets you on your way
northbound to destinations with challenge, fun, and adventure. Although this route takes you to many remote areas, services are well distributed so you should be able to maintain your supplies of food and water.
You will travel familiar yet enjoyable low traffic roads north up to Lake Roesiger. The sections of flats and rolling hills will get you and your legs warmed up. Pre-riders took a bathroom pause at Lewis Street Park (32 km) just after crossing the Skykomish River bridge into Monroe. (mind the bad tracks south of US2) You should make good time and arrive at the first information control at the Lake Roesiger Store (54 km). You can get food, water, and a bathroom here, but don’t linger long since you need to keep moving to hopefully see Mt. Shuksan in late afternoon light from the shores of Baker Lake.
You’ll be treated to quiet rolling roads through rural communities, particularly nice along Robe Menzel Rd into Granite Falls at 68 km. Various food and services can be found on route if needed, but no official stop is needed. You will eventually turn right onto Hwy 530 to point yourself to Darrington. Expect a decent road shoulder but passing vehicles are moving ~60 mph. Mind the rumble strips along the fog line and the random stones on the shoulder. At 99.4 km, turn right onto a 2-mile paved segment of the Whitehorse Trail and enjoy the views in peace and quiet away from road noise. Be careful on the wooden bridge deck over the North Fork Stillaguamish River. If wet, the wood can be slippery.
Enter Darrington and find the information control at the Fire District Station on the right side of road (132 km). The pre-ride team took the opportunity for a nice sit-down lunch at Moes Coffee across the street from the control. They have great breakfast, lunch, and snack options and a bathroom. If it’s cold and rainy, you might appreciate the break to get warm and dry since they have a large indoor seating area. Or you could ‘Rando-it’ and simply eat on the curb of the Shell gas station across the street – your call. Leave Darrington with full water bottles and food.
Giddy-up! Now adventure begins as you head to Marblemount. While the pre-ride started wet, we got treated to a dry sky and surprisingly warm conditions at this point. You’ll feel the remoteness on Rockport Cascade Rd but press on and enjoy the serenity. Fingers crossed you get blue skies and amazing snowcapped mountain views.
As you enter Marblemount, find the information control at Rustic Heart Desires on the left side of the road (177 km). Pre-ride team stopped briefly at the Chevron gas station for water and bathroom. With the anticipation (specter?) of Burpee Hill ahead, we got our group rolling to make some time down to Concrete. If you can get to Concrete by 4 PM – you could sneak into 5B’s Bakery and Eatery before they close. If not – there will be a staffed control at Baker Lake (227 km). If you need water and a bathroom before climbing *that hill*, they can be found at the Silo Spray Park just south of the intersection of Main St. and N. Superior Ave.
Burpee Hill Rd…. what’s there to say…it’s a legendary climb in the region. The pre-ride team all entered their individual pain caves and did whatever they had to do to slowly (very slowly) get our bodies and machines over this wall of a hill. We regrouped at the top and celebrated, but you are still far from the control so mentally stay in the game and press-on.
Given the route name, we thought it fitting to try something new and actually SEE Baker Lake, so we made a change to the traditional route and put a staffed Control at the Puget Sound Energy public access Boat Launch. This part of the route will be new to any veterans of past brevets to Baker Lake. At 224 km, turn right onto NF-1112 and follow the route cues and road signs to the PSE Boat Launch. Signage was good, road options are few, so you should not get lost. The control will be at the pavilion adjacent to the boat launch, you can’t miss it. Clean but primitive bathrooms are available. Water, food, shelter, and views will be available. If we have clear skies, you’ll have a front row view of Mt. Shuksan and Mt. Baker while you take a break.
Leaving the control, you will go around a gate and ride ~1 mile of ‘Cadillac’ gravel on top of a dike that forms the lake. This road is completely flat, no potholes, easily passible on 28 mm tires (even 25 mm if you’re still into those). Continue straight on this gravel road past a 2nd gate until you intersect a paved road. There are no road signs here, but this is NF-118, just turn left and ride uphill. Follow NF-118 back up to the main road and turn left again. When you get to the Shadow of the Sentinels, take a moment to look back at Mt. Shuksan if the sky is clear.
Now a different adventure begins. For most riders, it will be late afternoon or dusk (maybe dark). You’re in a remote area 170 km from the finish. You can feel the effort in your legs and now must steel yourself for the night shift. These are the moments that separate randonneuring from other cycling activities, embrace the challenge – you can do this.
The downhill plunge from Baker Lake to Hwy 20 will certainly be a nice pay-off for the climb up Burpee
Hill and sets you on your way home. You may want to layer up at this point for the long descent. If the
Hwy 20 passes are still closed, traffic should be modest, as few drivers will heading to/from the
mountains. Please exercise caution on Highway 20 as there are numerous spots where road debris is
plentiful, including branches, trash bags and other construction wood. You’ll make good time to Sedro-
Woolley with a slight downhill grade and direct routing.
As you enter Sedro-Woolley, find the information control at the Arco and AM/PM convenience store
(open 24 hours) at 282.9 km. The pre-ride team ate dinner at Subway (open until 10 PM) and resupplied
water and snacks. Next food/water is the 7-11 store (open 24-hours) in Arlington at 328 km so plan
Heading south out of Sedro-Woolley on Hwy 9 is the most direct way home but watch for some tight
shoulders and evening traffic. You’ll turn off Hwy 9 at W Big Lake Blvd for a nice respite on a quiet
section. Back on Hwy 9 you’ll roll through the familiar community of Lake McMurray and get to the
Centennial Trail head at 315 km. Mind the gate will be closed entering the parking lot (don’t crash into
it). Hopefully the familiar surroundings and safe trail will help motivate you – food and coffee in
Arlington awaits. Arlington bathrooms on the trail were closed at night.
The final information control on the road is the Snohomish Bakery and First and Union at 365 km. There
is a 7-11 store open 24-hours slightly off route in Snohomish at 1215 2nd St, Snohomish, WA – if you
need anything here.
The route takes you home on our conventional roads of Airport Way, up Springhetti Rd, then Broadway
Ave to Maltby (mind the bad tracks as the road turns left near Yew Way). Get yourself over ‘the three
amigos’ hills on 156 th Ave NE then plunge into Woodinville. Navigate onto the Sammamish River Trail
then the Redmond Central Connector trail and you did it! Roll into the Redmond Inn parking lot and
check in at the Finish Control.
400 km – easy-peasy.
Cell phone service at the Baker Lake info control is limited/spotty/nonexistent depending on carrier.
As always, bike checks for lights and proper reflective safety gear is mandatory. Please bring redundant light systems (dyno & battery backup or dual battery systems), we’ll be checking both. Someone on Spring 300 had a non-functional taillight and no backup, don’t let this be you. If it's wet and you don’t have fenders and/or proper ‘buddy flaps’, please be considerate of others and ride in the back of groups or ride solo so we don’t consume the road wash from your tires.
If you want a hotel room for post-ride sleep, please make your own reservations at The Redmond Inn
or other nearby hotels.

Electronic Proof of Passage
After you successfully complete this ride you may optionally submit your results by EPP. If you choose to do this you must complete and submit the Spring 400K EPP form
by Monday, May 9 at 6:00 PM (Pacific Time).
- The only EPP track data currently supported is via RideWithGPS trips. If you do not have a RideWithGPS account you can setup a free account. The trip must be marked "public".
- You must pickup a control card at the start.
- Your control card will be signed during safety inspection (verifying lights, reflective gear, etc). No safety inspection signature, no ride credit.
- After finishing, please sign your control card and write EPP clearly on the front.
- If the finish control is staffed, the organizer (or whomever is staffing the finish control) will record the time you rolled into the control as your finish time, then sign and collect your control card.
- If the finish control is unstaffed, you must note the time you roll into the finish on your control card and get someone to initial it. Note your ride completion time in hours and minutes.
- When filling out the EPP form ensure you enter the actual time you rolled into the finish control as your "finish time". Any "elapsed time" or "moving time" from your GPS is irrelevant for EPP purposes.
- This is still a trial – it would be wise to continue collecting info control answers as a backup.
If you wish to participate in the EPP trial please comply with these simple requirements.
