Get your Irish on and bring your patience as TriMet navigates riders to, through and from the Shamrock Run


Plan ahead for crowded MAX trains, delays in downtown Portland on Sunday morning, March 17

The Shamrock Run takes to the streets in and around downtown Portland on Sunday, March 17 and with 35,000 people signed up for the event, TriMet expects crowded trains and buses. Last year on the Shamrock Run day, ridership on the MAX alone was 52,000, up 14,000 over a typical Sunday that month. We want to remind riders the Free Rail Zone no longer exists; fares are required for all rides on MAX.

The big 15k kicks off the starting block at 7:40 with other runs and walks starting periodically through 9:10 a.m. Most of the events will have an impact on TriMet service. Thirteen bus routes will be detoured. MAX trains may be held for a few minutes to allow runners and walkers through. And, the Portland Tram will be running to get people up to Marquam Hill/OHSU. We ask riders to plan an extra 10 to 15 minutes into their travels.

With many street closures and detours in downtown Portland due to the run, TriMet also reminds drivers to use caution on the Transit Mall – 5th and 6th avenues. Please do not drive or stop in the “bus only lanes” and avoid making illegal turns and other unsafe maneuvers around buses and trains.

MAX Service

  • MAX will run on Sunday schedules.
  • Trains run every 35 minutes on certain segments of the MAX line during the early morning hours; Green Line service from Clackamas Town Center does not start until 8 a.m.
  • Riders should plan ahead. Check schedules or use the trip planner at
  • The closest stops to the Shamrock Run starting line are the Oak/SW 1st Ave platforms on the Blue and Red lines and the SW 5th & Oak and SW 6th & Pine platforms on the Green and Yellow lines.

Bus Service

  • Buses will run on Sunday schedules.
  • Thirteen bus lines intersect the Shamrock Run courses and will be rerouted in downtown Portland from 6:30 a.m. through as late as 11 a.m. The lines are 4, 6, 8, 12, 14, 15, 17, 33, 35, 44, 54, 56 and 77.
  • From 7:30 a.m. through 10 a.m., Line 8 riders traveling to Marquam Hill/OHSU will be shuttled to the South Waterfront to transfer to the Portland Tram, which will be providing special service during that time. TriMet fare will be valid on the tram.

Plan ahead

Avoid the need to make two purchases on Sunday by buying a day pass. It’s the same price as two 2-hour tickets.

Day Pass Fares
Adults:                        $5
Youth:                         $3.30
Honored citizens:       $2

Also, TriMet Customer Service staff will be on hand at the Shamrock Fitness Fair on Friday and Saturday, March 15 and 16, at the Oregon Convention Center. Runners can buy day passes for Sunday when picking up their race registration packets. Several bus lines as well as three MAX lines stop at or nearby the Convention Center.
