Portland Marathon presented by Nike Running.
The Portland Marathon presented by Nike Running is a bridge loop: four crossings of the Willamette, with downtown, the Northwest District, the Rose Quarter and the quiet tree-lined avenues around Reed College strung between them. The course is flat and USATF-certified, and its one serious climb waits exactly at halfway, just off the Sellwood Bridge.
Portland Marathon presented by Nike Running 2027: Course, Route Profile & Map
The start is on SW Salmon Street between 3rd and 4th, in the middle of downtown. North on SW 4th Avenue, a loop through Old Town and back down Broadway, and the highest point of the day arrives already at kilometre 3.4: 500 metres at 4.4 per cent up onto West Burnside Street at NW 23rd Avenue, 54 metres above sea level. Back east through the Pearl District, the route takes the Broadway Bridge at kilometre 10, loops the Rose Quarter and the Moda Center, and returns over the same bridge.
Then it stays flat for a long time: Naito Parkway along Waterfront Park, past your own finish arch at kilometre 13, on down Macadam Avenue into South Waterfront. At kilometre 19.5 the Sellwood Bridge is the low point of the loop at two metres, and immediately after it comes the decisive climb: 850 metres averaging 3.9 per cent with a 7.1 per cent pitch, 33 metres up onto the Sellwood Boulevard bluff. The half-marathon mark falls right inside it.
The east side is the rolling part. Bybee Boulevard and Crystal Springs lead through Eastmoreland, a short 380-metre ramp at five per cent follows at kilometre 25.4, then Reed College Place under old trees and, at kilometre 28, the Reed College campus with students lining the road. Milwaukie Avenue and the passage under the Ross Island Bridge bring you onto the Eastbank Esplanade at the water's edge, under Tilikum Crossing, between OMSI and the submarine USS Blueback, and under the Marquam Bridge. At kilometre 40.4 the fourth and final Willamette crossing goes over the Burnside Bridge, then Old Town, Naito Parkway, and the finish in Waterfront Park.

Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
How to pace Portland Marathon presented by Nike Running.
Start under control
Almost 55 per cent of the course sits inside the flat band and there is no steep terrain at all: 278 metres of climbing over 42 kilometres is 6.6 per kilometre. This is a rhythm race. Split it evenly and keep a clear reserve for the east side: treat the flat opening kilometres on Naito Parkway as a gift rather than an invitation to press, and you will still have them at kilometre 25.
Hold your rhythm
The race is decided between kilometre 19.5 and 31. The climb off the river onto the Sellwood bluff arrives exactly at halfway and, at 33 metres, is the only one that genuinely costs you; after it the rolling stretch through Eastmoreland and around Reed College never quite lets you back into an even rhythm. Hold effort constant there, not pace.
Spend what is left
Two traps are specific to this course. The first is the ramp at kilometre 3.4: 22 metres of climbing before you are warm, and in cool morning air it feels cheaper than it is; go with a group there and you pay for it at the Sellwood Bridge. The second is the measurement. The course is USATF-certified on the shortest possible route and turns dozens of times downtown; run wide and your watch will read well over 42.195 kilometres at the finish.
Training plan for Portland Marathon presented by Nike Running: 12-week build
Build the base
For a competitive age-group runner the effort lasts somewhere between two and a half and five hours. The demand is aerobic and even throughout: with no steep terrain there are no anaerobic spikes, but the course asks for the same pace discipline hour after hour.
Train race pace
The decisive sections are the climb onto the Sellwood bluff at kilometre 19.6 and the rolling east loop out to kilometre 31. Neither asks for climbing strength; both ask whether you can take short four to five per cent ramps on tired legs without letting your heart rate run away. Build ramps of 400 to 900 metres deliberately into the back half of long runs rather than the start of them.
Rehearse the course
Conditions are Pacific Northwest autumn in early October with a morning start, so you usually begin cool and run into the warmth. That is a clothing and drinking decision worth rehearsing, as is one long run in the wet.
Arrive fresh
The emphasis follows from that: long sessions at marathon pace on flat ground, pace transitions coming off the bridge ramps, and clean cornering. The course is measured on the shortest possible route, so hitting tangents is a trainable skill here and, across dozens of turns, worth several hundred metres.
