The Hypothermic Half Marathon is a signature winter running event organized by the Running Room, designed to encourage runners to stay active during the coldest months of the year. Held annually in cities across Canada, the Halifax edition is a favorite among local and visiting runners who embrace the challenge of winter racing. The event is known for its welcoming atmosphere, excellent organization, and unique amenities that make braving the cold worthwhile.

Participants can choose from a variety of distances, including the classic Half Marathon (21.1 km), a 10 km run/walk, and virtual options for those who prefer to complete their race remotely. The in-person event is chip-timed, and all finishers receive a commemorative medal and a special souvenir. A highlight for many is the post-race brunch, which provides a warm and social finish to the chilly race day. The event also features prize draws, including a chance to win Altra running shoes, adding extra excitement for participants.

The Halifax course primarily follows the Chain of Lakes Trail, a multi-use pathway renowned for its relatively flat and smooth terrain, making it accessible to runners and walkers of all abilities. The route starts at Ashburn Golf Club and features a moderate elevation profile, with gentle inclines and declines that provide some variety without being overly challenging. The trail is well-maintained and offers scenic views of the surrounding natural landscape, even in winter conditions. Participants should be prepared for typical February weather in Halifax, which can include cold temperatures, wind, and potentially icy patches on the course.
