START TIME:  9:20 a.m.



The Shamrock Half-Marathon field is limited to 3000 runners.

The new* Half course features these benefits:

  • A flatter and faster course using SW Naito and Barbur Blvd
  • Incorporates the entire 15k route, as before
  • Fewer turns and a creative way to reach the iconic Terwilliger Hills
  • Significantly less transit crossings – only 2
  • More downhill along SW Terwilliger

All Half finishers will receive a free commemorative Shamrock bottle opener medallion as they exit the finish area.

*UPDATES FOR 2017:  The Shamrock Run will feature new routes for all distances!  We have been required by the City of Portland to redesign our courses because of severe police staffing limitations.
