YYC Sub Ultra Trail Run 2026

The YYC Sub Ultra Trail Run takes place on August 30, 2026 in Calgary, Alberta. Organized by RnR Premiere Events, the one-day event celebrates sub-ultra distances — races shorter than a marathon that have surged in popularity — and centers on the city’s trail-running community around Nose Hill Park.

Runners choose from a 34 km, 17 km, 6.8 km and a 2 km kids run. The 17 km distance includes a dedicated Wild Rose women-only field, and the main distances begin with a mass start at 7:00 a.m. MDT on race morning. The kids 2 km is listed as an untimed event, making it a family-friendly addition to race day.

What distinguishes YYC Sub Ultra is the combination of compact sub-marathon challenges and genuine prairie-trail terrain inside Calgary. Courses weave Nose Hill Park’s rolling singletrack and service paths, offering prairie outlooks without a long drive from the city. Organizers position the race as an accessible step into trail ultras for first-timers while still providing a stout 34 km option for runners seeking a concentrated endurance test; the women-only Wild Rose 17 km and untimed kids run add community-focused choices.

Registration uses tiered pricing with the final registration window listed through August 29. Runners should check entry deadlines and sign up early to secure the preferred distance.
