Route description
Route description

Shamrock Half Marathon:
With a course containing minimal turns and plenty of downhill, the Half boasts a truly picturesque journey into the famous Terwiliger Hills - now with only two road crossings.

Shamrock 15k:
The 15K route features much of the Half route, including plenty of downhill and the final stretch into Terwiliger Hills.

Shamrock 8k:
The 8K contains an out and back route, beginning at SW Pine and culminating at SW Naito. With one solitary turn on the route congestion will be minimised for those tackling this one

Shamrock 5k:
5k runners can expect to be going off first, again with only two on-couse road crossings and one turn around point. The finish is at SW Naito and Yamhil

Kids Leprechaun Lap 1K:
The Kids Fun Run is an out and back along SW Naito.

Logistics and schedule

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.

Here are the ways to get your bib number and t-shirt before race day:

Join a Team of 12 or more! Team captains get lots of perks, and team members get all bibs and t-shirts shipped to the Team Captains so you get yours before anyone else during the first week of March.
Non-team members can get their bibs and t-shirts at the Shamrock Run Fitness Fair, presented by Moda Health, in Exhibit Hall A/A1 at the Oregon Convention Center. For runners, your timing chip is attached to the back of your bib number.
Have a friend pick-up your bib for you at the Shamrock Fitness Fair (non team members only). If you need a friend or family member to pick up your bib, please be sure you have:
Signed the electronic waivers in your account.
Provided them a copy of your registration confirmation email (email copy is fine).
Provided them a copy of your photo ID (photo via email or text is fine).

Specific timings of each of the events have yet to be decided, but will be sent out closer to the event.


There are great opportunities to spectate all along the course - just make sure that if you plan on driving you allow plenty of time before the race start to avoid the road closures - driving even on the morning before the race is hugely discouraged.
