Course & elevation
Portland is mostly flat through the city core, with the notable grade coming from the bridge crossings over the Willamette River. It’s a comfortable, scenic course rather than a pure downhill speedway.
- Start → Finish
- 60 → 55 ft
- Net
- −5 ft
- Total gain
- ≈ 873 ft
The certified route
A complex of loops through Portland, starting downtown on SW Salmon St, heading south along the waterfront on SW Naito Pkwy and the Eastbank Esplanade, across the river to the east side neighborhoods and Reed College, south to the Sellwood Bridge turnaround, then north across the Broadway Bridge through the Pearl District and past the Moda Center, finishing at SW Taylor St.
- Start
- SW Salmon St, 15 ft east of the west edge of the pedestrian sky bridge between SW Naito Pkwy and SW 1st Ave.
- Finish
- North end of SW Taylor St at SW Naito Pkwy, 5.2 m south of lightpole CCP D11-0381 388, also 9.1 m north of the manhole.
Underfoot
Paved, 100 percent.

What you pass
- The Broadway Bridge crossing
- The Eastbank Esplanade along the Willamette River
- The Sellwood Bridge turnaround at the south end of the course
- Reed College, passed on the east side loop
Worth knowing
- The course was originally measured in August 2019 and adjusted in July and August 2023.
Transcribed from the USATF certificate for Portland Marathon (OR19001JH), measured 18, 25, 27 and 28 August 2019; 30 July, 6 August and 13 August 2023. Where the certificate is silent, so are we.
Key moments
- Mile 1–8Flat downtown and industrial miles. Ease into rhythm.
- Mile 12–18River-crossing bridge ramps provide the only real grade.
- Mile 24–26.2Back across the river to a downtown finish.
Pacing strategy
Run the bridge ramps by effort and keep the flat middle controlled. An even pace suits the gentle profile.
Pacing by goal time
Checkpoint splits for four common goals at Portland Marathon. These are effort-even rather than pace-even: the paces shift with the course profile, so climbs are slower and descents faster by the amount the grade actually costs. For any other goal time, use the planner below.
| Checkpoint | Sub-3:00 | Sub-3:30 | Sub-4:00 | Sub-4:30 |
|---|---|---|---|---|
| Mile 3.1 | 20:376:49/mi | 24:037:57/mi | 27:299:05/mi | 30:5510:13/mi |
| Mile 6.2 | 41:136:54/mi | 48:068:03/mi | 54:589:12/mi | 1:01:5010:21/mi |

| Mile 12.4 | 1:22:226:49/mi | 1:36:067:58/mi | 1:49:509:06/mi | 2:03:3310:14/mi |

Splits assume even effort and are adjusted for this course's climbs and descents, which cost more than they give back. A model, not a promise: wind and heat move real splits around. See how the pacing model works.
Plan your mile splits
Turn your goal time into a mile-by-mile plan for Portland Marathon, built from this course's elevation. The even pace approach comes pre-selected, and grade-adjusted pacing evens out your effort across the climbs and descents.
Plan Portland Marathon splitsFueling & hydration
Aid stations roughly every 2 miles with water and sports drink. The steady terrain makes a fixed gel schedule simple to follow.
Weather
Early-October Portland is typically cool and possibly damp, making for good racing conditions.
What race morning has actually been like
The last 5 editions of Portland Marathon, measured at the start line rather than averaged across the month. Starts have run 43–55°F, averaging 49°F.
| Year | Date | Start | Dew pt | Wind | By late morning |
|---|---|---|---|---|---|
| 2021 | Oct 3 | 49°F | 48°F | 2 mph | 59°F |
| 2022 | Oct 2 | 55°F | 56°F | 5 mph | 74°F |
| 2023 | Oct 1 | 45°F | 47°F | 3 mph | 55°F |
| 2024 | Oct 6 | 43°F | 51°F | 4 mph | 59°F |
| 2025 | Oct 5 | 52°F | 51°F | 4 mph | 58°F |
The gap between the gun and late morning matters here. In 2022 it went from 55°F at the start to 74°F by late morning. A four-hour finisher ran a materially different race from a three-hour one.
Dates derived from the race's published pattern (1st Sunday in October), observations at Portland, OR. Source: Open-Meteo historical reanalysis (ERA5), 7-11am local at the start line. Reanalysis is modelled from station observations, so treat it as a close record rather than an official one. See how race-morning weather is built.
Is Portland Marathon a good Boston qualifier?
Yes. The course drops 5 ft net, comfortably inside the 1,500 ft threshold where Boston's downhill adjustment begins, so a time here is submitted as run.
This drop is our estimate rather than a figure from the course's certificate. If it sits near a threshold, confirm with the organizer.
Compare every course, how the downhill bands work, or work out your own target.
