The Bog Slog, now in its 43rd year, is the extra tough and extra muddy halftime race to the Winter League, and a fantastic opportunity for students who have graduated from WIOL to return for a holiday reunion with friends!
The Bog Slog concludes the Choose Your Adventure Series, which means that we are offering two mass-start, point-to-point courses (The Bog Slog & The Bog Jog) for the advanced navigators, as well as a Choose Your Adventure style race for beginners, intermediates, and trail runners!
This year, as in recent years, we will have a separate mass start for each course. See the schedule for course start times.
If you’re a runner, this means an opportunity to stay with similarly-paced runners on the same course until elevation gain and navigational challenges split the pack.
If you’re a hiker, this means that you don’t wait long for a start, and the herd of running orienteers departs rather quickly, leaving you with a nice hike-with-a-purpose through Lord Hill Park.
As always, The Bog Slog advanced courses are longer and more challenging than our usual Winter League courses. Some participants drop down a level for ease, while others treat this as the ultimate challenge, often sharing the navigation fun and bragging rights for completion.

The Bog Slog (Long Advanced) and Bog Jog (Short Advanced) courses are point-to-point, meaning that you need to visit the checkpoints in a specific sequence. Fastest time wins. Most checkpoints will require off-trail navigation.
The Choose Your Adventure course (intended for beginners, intermediates, and trail runners) is freestyle, meaning that you can visit as many checkpoints as you can, in any order that you like, until the course closes. Most checkpoints are on or very near trails.
ESTIMATED RACE DISTANCES (based on last year, 2022 details to be posted soon): The Bog Slog (Long Advanced) – 7.6 km, 18 checkpoints, 490 m climb, 1:10000 scale map The Bog Jog (Short Advanced) – 4.9 km, 13 checkpoints, 310 m climb, 1:10000 scale map
Choose Your Adventure – 24 checkpoints, 3 hour time limit, 1:10000 scale map. The course is a mix of some easy-to-find checkpoints, some intermediate checkpoints, and a few advanced checkpoints.
The start for all courses is up the hill at the quarry, approximately 500m (and a 65m climb) from parking & check-in.
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.
How does the scoring work for Choose Your Adventure course?
All 24 checkpoints are worth the same amount: 1 point per checkpoint. The maximum score is 24 points. The first person or team returning with 24 points wins!
There’s a time limit of 3 hours, and for every minute late, there’s a 1 point penalty.
COURSE & MAP NOTES
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.
Lord Hill is a popular park for mountain bikers. Many of the trails are multi-use and shared, so be aware of your surroundings and look and listen for them. In the north area of the map, there is a hill with some trails marked out of bounds (purple X’s). These trails are One Way trails (downhill only), on which mountain bikers ride VERY FAST, exiting onto the shared trails. We’ve designed the courses to avoid these areas and make traversing them a dubious or unattractive route choice.
All rootstocks and tree stumps have been removed from the map used for this event. Hundreds of rootstocks and tree stumps were mapped, back in 2011, now over 10 years ago. Since then, windstorms have created many new unmapped rootstocks, some rootstocks and stumps have withered away into knolls, and some stumps have large trees re-growing from them, so they really aren’t stumps anymore. We don’t want orienteers frustrated with this major inconsistency of the map, and we don’t have the time to re-map every rootstock and stump over a huge area, so we decided to remove them. In addition to being more consistent, the map also benefits by being significantly more legible. Use the contour lines!
Vegetation has also changed over the years. While generally accurate, some light green areas have become thicker (“greener” than mapped) and other medium green areas have become quite passable (“lighter” than mapped).

$22 base price
– subtract $5 for CascadeOC members
– subtract $5 for using your own 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!
Online pre-registration closes: 9:00pm Thursday, December 29
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.
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.
