This event is pre-registration only which closes 11:59pm Friday, December 25.The Bog Slog, now in its 46th 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.
