2018 Route Information (subject to change)

The Shamrock Run will utilize our routes for all distances that were developed by the City of Portland due to police staffing limitations.

Note that the Shamrock Stride 4-Mile Walk will have its own route and will not follow a run course.

Starting Procedure for All Events

All Shamrock events (except the Leprechaun Lap) will be started with a “release and hold” system. Runners are to line up behind their appropriate per-mile pace sign held overhead in the assembly area. Runners will be released in groups of 500 to 1000 participants every 30 to 90 seconds to allow the field to spread out and to minimize congestion along the route, especially in the first mile.

The chip-timing system will not record a starting time for a runner until that runner has crossed the timing mats at the start line. Time spent waiting to cross the start line is NOT included in the scored finish time for a runner.

All race distances are USATF-certified.
