The 2026 Frigid 10K and Frosty 5K is a signature early-season running event in Hamilton, Ontario, offering both in-person and virtual race options. Traditionally linked to the Chilly Half Marathon, these races have evolved into a standalone event to accommodate more participants and provide a focused race-day experience. The event is known for its welcoming atmosphere, drawing runners of all levels to challenge themselves on a scenic road course along Hamilton's waterfront.

Participants can choose between the Frigid 10K and the Frosty 5K, with both distances available as in-person or virtual races.
