UPDATE, May 2021: Bellingham County Parks is finalizing our permit so we are moving forward with the August 14-15 dates based on other Bellingham events happening in August. It’s looking optimistic we will be approved with Covid policies in place. Registration will open Thursday, May 13th – updates will be made here and on both Instagram and Facebook Walla Trails social media pages. Space is limited to accommodate 2020 rollovers and meet COVID guidelines. UPDATE: The 32 Hour Race is SOLD OUT.

There will not be a Hamster Endurance Runs virtual option this year. We need to give full attention to making sure the in-person event goes safely and smoothly. We apologize for anyone looking forward to getting loopy with us from afar!

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 2021 Hamster Endurance Runs will be happening on August 14-15 and be giving to the Whatcom Family YMCA Girls on The Run Program. Registration opens Thursday, May 13th 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 – 2021 update
Due to Covid restrictions, expect to see a lot of individually packaged items. From individual packets of potato chips, various Hammer, Clif, and Stingers gels, granola bars, gummy bears, etc., to warm options at night like pizza, vegan soup, coffee, hot cocoa, and pancakes in the morning, vaccinated volunteers will be ready to serve you! There will also be limited gluten free options. We highly 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.

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.

There are several businesses, local and nationwide, that are supporting Hamster Endurance Runs!

  • FAIRHAVEN WALKERS & RUNNERS – Fairhaven Runners & Walkers has been supporting and serving the Bellingham running community for 22 years. Women and men’s winners for each race will receive a $25 gift card and each runner will get a discount coupon to use on their way out of town!
  • PRIME SPORTS INSTITUTE We feel very fortunate to have a business like Prime Sport Institute in Bellingham! Prime provides “athletic therapy to optimize performance, prevent injury and enable recovery.” Hamster Runners can take their bib number to Prime and receive a discounted recovery session and get a tour of what Prime has to offer.
  • ITHACA HUMMUS We are hummus connoisseurs at Walla Trails and when we tried the Lemon Dill Hummus from Ithaca Hummus, we knew runners had to give this a try! There will be Lemon Dill Hummus wraps at the aid station and every runner will get a coupon for a free 10oz tub of Ithaca Hummus.

Q&A // Rules

  • What is Walla Trails doing to keep runners safe pre-event, during the event, and post-event? UPDATED RACE WEEK: We will follow the Governor’s guidelines for outdoor events. We recommend that you read over this document. Here are some of the key safety measures: Volunteers will be pre-screened before the event
  • All volunteers are vaccinated and use hand sanitizer during check-in and at the aid station
  • Hand sanitizer will be available at the start/finish/aid station area
  • Social distance of six feet or more will be maintained when possible
  • What is Walla Trails asking runners to do pre-event, during the event, and post-event? Here are some of the key safety measures we need all runners to follow: Stay home if not feeling well
  • Runners who are not vaccinated will wear a face covering at the start, and during the event when coming within 6 feet of volunteers or other runners
  • Please use hand sanitizer as soon as you arrive, after you use the restroom, and after you finish the race
  • Travel and stay with family or those in your social distancing circle
  • Are spectators allowed? Unfortunately this year, no. Our permit only allows runners and approved volunteers. HOWEVER, if you’d like a friend or family member to be present at your race, have them volunteer! In 2019, we had some amazing help from family standing around waiting from their runner. Email wallagretchen@gmail.com to see how we can create a win-win situation!
  • Are pacers allowed? Yes, pacers are allowed for the 32 hour and 24 hour events once the 12 hour event is wrapped up a little after 8pm Saturday. Only one pacer at a time but a runner may have more than one pacer help.  We may have to ask pacers who are waiting to relieve another pacer to either 1) come right before they are ready to pace their runner, 2) wait in their car, or 3) help at the aid station while they wait.  Currently the permit doesn’t allow spectators so we can’t have pacers standing around. 
  • Are dogs welcome? Yes, on a leash! Dogs must like people and other dogs. If dogs are running on course, they must be kept on leash due to park rules. There is also a dog park nearby.
  • Can I set up a tent to nap in if I am running the 24 or 32 hour race? No shelters of any kind are permitted due to park rules. However, you are welcome to nap in your cars or near the shelter at any point in time.
  • What if the race is cancelled due to COVID? We will offer rollovers for 2022 or 75% refund pending recouping costs of permit, insurance, and rentals.
  • Are there refunds? Yes:
    • 95% refund by June 30 (we account for time and fees to mail a refund check)
    • 50% refund by July 31
    • No refunds on or after August 1st
  • 2020 Rollover Info:
    • Runners who asked for a rollover will be given a code to re-register for 2021. Email wallagretchen@gmail.com if you have not received instructions on how to rollover your registration by May 15th
    • If August 14-15 does not work for you, registration can be rolled over in 2022. Email wallagretchen@gmail.com for other options.
