Portland Marathon | Half Marathon
October 5, 2025 @ 4:30 am - 1:00 pm PDT
An event every year that begins at 4:30 am on day first of October, repeating until October 5, 2025
The Portland Marathon by OHSU event includes a full marathon as well as a half marathon. Both races start and finish at Portland’s Waterfront Park at 1000 SW Naito Pkwy at the intersection of Naito Pkwy and Salmon Street. Both courses offer a fast elevation profile with the start/finish line only 36 feet above sea level, and a maximum course elevation of just 178 feet.
RACE START TIMES
Beginning at 6:40 AM all runners may line up in the start chute on Naito Pkwy. The start chute will stretch from Salmon St to Columbia St and will be divided down the center of the road with the half marathon staging on the west and the full marathon staging on the east. Large markers denoting various paces will line the start chute and runners will be directed to queue in the zone which marks their expected pace. The fastest pace group will line up closest to Salmon St and the slowest pace group will line up closest to Columbia St.
Both races will begin, en masse, at 7:10 AM.
