TTUAH - Trail Terrier Ultra Around Hamilton 2026

TTUAH — Trail Terrier Ultra Around Hamilton is a 100-mile trail ultra based in Carlisle, just outside Hamilton. The event is built around a full-city circumnavigation, with runners moving through the communities that make up Hamilton on a course that leans into long-haul trail endurance.

The 2026 edition is set up as a flexible ultra challenge, with an all-at-once option for runners aiming to finish inside the 40-hour window, and a longer completion window for those breaking the distance into stages. That makes it a rare kind of local ultra: ambitious, but still shaped around different ways to get the mileage done.

For runners looking for a trail event in southern Ontario with a strong distance focus, TTUAH sits squarely in that space. It’s a straightforward ultra concept with a clear route identity and a finish-on-your-own-terms feel.
