August 2022 UPDATE: All races are sold out // REGISTRATION CLOSES – August 9 – Register via Ultrasignup. Waitlists are started. Race weekend is August 13-14.

Hamster Endurance Run 6/12/24/32 hour event was created in 2013 by Kelly Krieger. Kelly found it to be a fun and loopy way to run miles while raising money for local organizations. In November 2018, Kelly was searching for someone to take over Hamster and found yours truly. The 2022 Hamster Endurance Runs will be happening on August 13-14 and be giving to the Whatcom Family YMCA Girls on The Run Program. Registration will open early to mid-January on Ultrasignup.

After several years of directing Hamster, creator Kelly Krieger finally ran her own race!

Course, Directions, Parking & Lodging

The ​​​​​​​​course will be the well marked 2.6 mile trail that circumnavigates Lake Padden. The trail will have obvious markers and additional glow lights for the night time hours. The trail is a wooded, natural setting so it’s required that runners come prepared with headlamps. Trail surface is compact dirt and/or crushed gravel, nontechnical, with minimal elevation change. Each loop has 244 ft. of elevation gain.

Race support will include a variety of food, water and electrolyte drinks. // Aid Station – 2022 update
There will be a variety of individually packed snacks, chips, gels, and more. Back by popular demand, a variety of wraps will be available including peanut butter and pickle (don’t knock it until you try it!). We will also have hot food and beverage options at night and Sunday morning for 24 & 32 hour runners. Updates will be shared as we get closer to the race when we know whether we can use portable stoves. We also encourage runners to bring their own fuel if there are special dietary restrictions and can not risk any cross contamination. We will have a large drop bag area, and runners will be welcome to use designated picnic tables under the shelter. There will be gluten free and vegan options!

Tent camping is not allowed outside the shelter but runners are allowed to take naps in their cars. 24 & 32 hour runners – we will only be allowed a few runners to rest during the night under the shelter. Based on Hamster history, this has not been an issue as runners spread out nicely. However, we encourage those going the distance to think of your car as a second aid station!

Runners will be able to exit and enter the course only at designated areas.
