Course Markings


  • The course is marked primarily with orange flags and orange ribbons accompanied by green or checkered blue/white ribbons (see photo).

  • For legal reasons, our flaggers must stop runners at all road crossings. Please be patient and heed their authority. Runners that do not stop will be disqualified from the race.

  • The trails are open to the public. Please be respectful of other users (non-race participants) using the trails.

  • There is an 8 HOUR time limit. CUTOFFS: Anyone arriving at Aid Station #4 (32.7km/20.32M) after 2:30pm will be offered a ride to the finish. Aid Station #5 (40km/24.85M) will close at 3:00pm.

In an effort to make our race more environmentally sound, we work with Zero Waste to minimize trash. For this reason, we will not provide paper cups for water, cola and/or electrolyte drinks.  All runners are responsible for carrying their own refillable hand-held bottles or hydration systems. Ultimate Direction Body Bottles will be available for purchase (at a discounted price!) at the Friday night and Saturday morning packet pick-ups.

No Pacers

Please only run this race if you have an assigned Chuckanut 50k bib number.  Our permits allow us to have a set number of runners on the trails and we are unable to allow additional pacers, runners or self-supported runners on the course. Thank you for honoring this rule.

4-legged friends

Due to insurance and facility reasons we are not allowed to have dogs at any part of the race event. Thank you for leaving your pups at home and honoring this rule.

Drop Bags

Due to access and field size we do not provide drop bag service on the Chuckanut 50k course.  Thank you for your understanding.

If you would like to put post race clothing in a dry bag for the finish line, we will have a location at the start/finish line for you to store your bag. You can drop off the bag when you arrive to Fairhaven Park on Saturday morning - please make sure the tag from your bib is securely attached to your bag. Please do not store any valuables in your bag. We will do our best to monitor all bags, but we cannot be held liable for lost or stolen items.


Each year we have an amazing crew of volunteers that seem to have a blast no matter the weather.  These people make the race possible, and we are so thankful for their support. This race could not happen without our volunteers and their energy. Be sure to thank every volunteer you can! If you are interested in volunteering, please complete our Volunteer Google Form. Our volunteer coordinator, Kevin Douglas, can be reached at lostlake50 at

Finish Line

Various sponsor and supporter tents will provide information and free product samples. We'll also have open-sided tents set up to provide shelter so that you can recover, eat, drink, chat and cheer in your fellow Chuckanut 50k runners.

Friends, family, community members and all interested are invited to take part in our finish line activities! Due to insurance and facility reasons we can not allow dogs on course or at the start or finish line. 


If you are unable to attend the race please let the race director know at chuckanut50 at before Wednesday, February 20 to receive an entry refund less $25. If you pre-ordered a shirt, we will be happy to send it to you. We do not allow entry roll-overs or transfers and are unable to issue refunds after that date.

Wait Listers

We do our best to get the entire waitlist into the event, permits pending. We have a refund policy (see paragraph directly above) so we will have a good idea of how many currently registered participants will not be able to join us by February 20 and make the major shifts by February 22. Waitlisters will receive an invite email from UltraSignUp to accept or decline a registration. If accepted your card is charged at that time.

Special requests

All runner (late entry, elite requests, etc) and sponsor special requests must be received no later than February 15 to be considered.

Event cancelation

In case of cancellation of the event, for whatever reason, decided more than 14 days before the date of the start of the race, a partial refund of the registration fees will be made to currently registered runners. The amount of this refund will be fixed so as to allow the organization to cover all irredeemable expenses committed, up to the date of the cancellation. In case of a cancellation decided less than 14 days before the start, or in case of interruption of the race, for whatever the reason, no refund of the registration fee will be made.
