Course

Flat and fast rural course through the Skagit Valley.  The marathon is a Boston qualifier with a certification course number of USATF # WA21009RMB. The half marathon is also certified with a course number of USATF # WA19017RMB .  The race start is on Victoria Street on the south side of Burlington Edison High School.

The Skagit Flats marathon course is designed to favor roads with less traffic and lower speed limits. The marathon and half marathon are run on rural roads through the Skagit Valley farmlands (see course map for exact route) and finish on the Burlington-Edison High School track. The course will be clearly marked, with monitors at all intersections. Due to course restrictions, participants must finish within 6 hours. The course closes at 2:15 pm.

The 5K start and finish is at the same location as the full and half marathon.

Course Narrative:
Start on Victoria Street just west of the gym and make a left on Norris street. Continue under I-5, go straight at the stop sign, and after about 1 mile take a right on Pulver. Go straight through the next stop sign at Josh Wilson and then make a left on Maiben. Right on Avon-Allen, then a left on Benson.  After about a mile and a half the full marathon turns off to the right (North) on Thomas road.  The half continues about three quarters of a mile to a turnaround point and returns via the same route.  The full marathoners will follow Thomas road north to a turnaround point at Sunset Road, return south on Thomas, turn right (west) on Field road, right (north) on Church road to a turnaround point at Farm to Market road and return to Thomas road.  Runners will turn right (south) on Thomas, turn right (west) on Benson and continue straight across Allen west onto T-Loop Rd to a turn-around point.  After you turn around you will follow the course back on T-Loop, Benson all the way to Avon-Allen and continue to backtrack the route you came out. When you get back to the starting line, you will make a left and run between the gym and track and onto the track.

Course Closure:
The course will be open for 6 hours. All participants must finish the race in 6 hours. Runners and walkers who have not finished by 2:15 pm will be responsible for their own safety.  Participants receiving support from bicyclists, unregistered runners or unofficial vehicles will be disqualified.

Aid Stations:
There will be full-service aid stations located along the course. There will also be water stations near miles 12 and 18 at the last two full marathon turnaround points. The full-service aid stations will be staffed by local cross-country teams. Water, FLUID Performance sports drink, and Honey Stinger Gels will be available at these aid stations.

The approximate positions of the aid stations for the full marathon course are as follows: 1.25 miles, 3.75 miles, 5.75 miles, 7.75 miles, 9.75 miles, 11.75 miles (water only), 14 miles, 16 miles, 18 miles (water only), 20.25 mile, 22.5 miles, 24.75 miles.

Porta Potties:
We will have porta potties along the course, located adjacent to the aid stations.
