YYC Sub Ultra

Looking for a trail race that’s adventurous, achievable, and shorter than a marathon? That’s exactly what the YYC Sub Ultra Trail Run is all about: a sub ultra is simply a trail distance under 42.2 km, and it’s quickly becoming one of the most popular ways to experience trail running without committing to a full marathon or ultra.

Hosted in Calgary’s iconic Nose Hill Park, this event delivers big trail energy, beautiful views, and a supportive community vibe, whether you’re a first-time trail runner, a road runner trying something new, or a seasoned trail athlete looking for a fun challenge.

Choose Your Distance: 34 km |17 km | 6.8 km

Who It’s For:

This is a trail walk/run experience built for all levels - come to challenge yourself, explore new trails, or simply enjoy an unforgettable day outside with the Calgary trail community. (Note: the event also offers specific waves/divisions noted on the event site, including a women’s-specific wave and a kids division that is un-timed.)
