Seaport Striders Lewis-Clark Half Marathon & 5K Fun Run Race Description

The Seaport Striders' 25th Annual Lewis-Clark Half Marathon & 5k starts at 9 am on Oct 14, 2022. 

Course closes at 12:15 pm.  8:30 am early start is ONLY for half marathon participants who cannot finish by 12:15 pm.  Early start MUST be coordinated with Race Director before starting.  Failure to coordinate will result in no official time.

Check-in & same-day registration is from 7:30-8:30 am at Granite Lake Park. The park is located at 848 Port Way, just north of the Clarkston Holiday Inn next to the Snake River.

Both the Half Marathon and 5k routes are out-and-back courses along the Snake River on the Greenbelt Trail System.  This paved trail is mostly flat with multiple water & bathroom stops available.

Late fee applies to all entrants after October 7th. You must register by September 24th to guarantee a shirt.  No refunds.

Seaport Striders Club members received a $2 discount.

Awards to Top-3 male and female finishers for each distance & age-group ribbons will be awarded.  Medals for Half Marathon finishers.

Kids' Run

We are pleased to again hold a free 1 mile Kids' Run! Kids will start at 8:30am so guardians can warm up with a child in the Kids' Run and then participate in the 5k or Half Marathon. For the Kids' Run, we will announce times as children finish, but not report times publicly. Participants will be issued bibs and receive a participation award.

For more information, contact the race director, Romney, at Debbie@RomneyH.com.  Visit our website, www.seaportstriders.com, for more club information.
