The Chill Session 2025 is a festive trail running event hosted by North of 89 Outdoors at the Mansfield Outdoor Centre in Mulmur, Ontario. Participants can choose from a 10K trail run, a 5K trail run, and a 1K kids run for children under 10. Each registration includes a Canadian-made hoodie, a medal, and a post-race meal featuring chili and beer.
