**Grit & Grind Trail Series**, presented by Arc'teryx, is a Wednesday evening trail race built for those who crave hills. The 2026 Carlington Hill edition brings a challenging 5K trail race and a 2K kids run to an Ottawa-area trail setting — expect steep climbs, fast descents, and the electric atmosphere of racing in the woods after work.

This is a true trail race with significant vertical gain, and the organizers don't sugarcoat it: expect climbs. Runners are rewarded with the full trail experience — a marked course, chip timing, a commemorative medal, personalized bib, and post-race refreshments. A Green Bib option is available for those who prefer to support charity rather than receive a medal.

The kids 2K is a fantastic introduction to trail running for young adventurers ages 5-12, though children must navigate the course independently — parents are welcome to run alongside younger kids. The Grit & Grind Trail Series is presented by Arc'teryx, one of Canada's most respected outdoor performance brands.
