The Bog Slog, now in its 41st year, takes on a special significance this year, as it may be our first in-person event since the start of the COVID-19 pandemic in March.

The club has developed COVID-19 operating protocols which are currently (as of 11/23/2020) deemed satisfactory by the State of Washington’s governor’s office and Snohomish County Parks.

However, conditions and infection rates may change between now and the event date of Saturday 12/26/2020.  Cascade’s board will make a final decision on Thursday 12/17/2020 about whether or not to hold the event. If the event will happen, we will open online pre-registration at 4pm on Friday 12/18/2020.

If the event does happen, be prepared for the club’s operating protocols, which will include things such as:

  • Participant limits (no more than 60, and it may be less)
  • Mandatory online pre-registration (no day-of-event registration allowed)
  • Participants must provide their own e-punches and compasses (no rentals)
  • Pre-assigned start times with intervals of 2 minutes between starts.
  • No pre-race or post-race gatherings. Stay in your vehicle until 10 minutes before your start; head back to your vehicle after you finish.
  • Masks must be worn at all times except when competing on the course.
  • Carpool only with people from your household.

In the coming days, we will link our club’s COVID-19 operating protocols and provide a very short, two-question survey about your interest/input for the event.


All courses this year are point-to-point, meaning that you need to visit the checkpoints in a specific sequence. Fastest time wins. For the Slog and Jog, most checkpoints will require off-trail navigation. The Clog, for beginners, will have most checkpoints are on or very near trails. There is no Choose Your Adventure course this year (since all of the other Choose Your Adventure events were canceled).

How are point-to-point courses measured?

Courses are measured as the crow flies, in a direct line from checkpoint to checkpoint. Unless you have wings, you will travel farther than this distance! Courses are measured in kilometers, so a good rule of thumb is to simply round up to miles to estimate how far you will go. So in a 5 kilometer race, you’ll likely travel up to 5 miles.


Lord Hill Park is a large wooded park with a great variety of vegetation and an extensive trail system. Trails vary from wide gravel roads to narrow trails. Vegetation varies off trail from run-able to fight. Full body cover is recommended.

Hazards include slippery trails, steep elevation change and varying levels of vegetation on the off trail routes. Be wary of icy patches in cold weather.


Exact schedule TBA.

There is no day-of-event registration for this event.


What’s an e-punch?

An e-punch records your race. At each control, you’ll dip the e-punch into an electronic box, which will beep and flash as confirmation. After you finish, you’ll download the e-punch at the download tent and get a receipt that show which controls you visited and how long you took between each; these are your “splits.”

Part of the fun of orienteering is comparing your splits with people who completed the same course, and discussing the routes you took!

Volunteers make these events happen! You can volunteer and participate on the same day, plus earn volunteer points to earn a free meet.


Parking will be in the south lot of Lord Hill Park, near the river, accessed from Tester Road. No special parking passes are required.

To prevent the spread of COVID-19, please do not carpool with people outside your household.


Covering 1,463 acres of forest, ponds, and open meadows, Lord Hill offers some of the best navigation west of the Cascade Mountains. It features rolling hills, a wide-ranging trail network, and enough navigable land to have back-to-back events on a 1:10,000-scale map with little to no overlap.

Though Lord Hill has north and south entrances, the club routinely uses the southern entrance for its ample parking and closer access to “the bowl,” an open, grassy area ideal for the arena-style finishes used in larger events.

Since 2014, Lord Hill has been the preferred location for the annual Bog Slog during the winter, and is often used for another event during the year as well.

Return to the Finish
All participants MUST return to the finish and download their e-punch or turn in their punch card.

Even if you have not finished your course, you must still return to the the finish and confirm with event staff that you have returned safely.

Out of Bounds
Some areas may be marked out of bounds. It is imperative to respect these boundaries to maintain our relationships with land managers. Participants MUST NOT go out of bounds. Any participant caught going out of bounds will be disqualified.

Course Closure
All participants MUST return to the finish by course closure time. If a participant does not return by course closure, event volunteers will begin coordinating a search party.

If you need a long time on the course, start as early in the start window as possible, wear a watch, and be prepared to cut your course short to make it back by the course closure time.

All participants MUST carry a whistle on the course. Complimentary whistles are available at the start tent (please only take one).

If you are injured on the course and need assistance, blow three long blasts to call for help.

If you hear a call for help, abandon your course to find the person in distress.

Part of the fun and fairness of orienteering is navigating your own course, so please be polite when you find a checkpoint and don’t holler that you’ve found it.
