About the event

Experience the uniquely festive One of a Kind Onesie Run as it returns to Calgary's vibrant downtown area on November 14, 2026. This quirky race caters to runners and their furry friends alike, providing an unforgettable day filled with laughter and camaraderie.
The event kicks off in the heart of downtown Calgary near Stampede Park, just a stone’s throw away from the bustling intersection of 5th Avenue SW & 7th Street NW. Participants can expect morning temperatures between -5°C to 2.7°C, averaging around -1.6°C, creating an ideal chilly yet comfortable environment for those dressed in their cozy onesies.
The park setting offers a picturesque backdrop, perfect for both adults and children. The course features firm terrain that feels like walking on plush carpet due to its cushioning nature, making it easy and enjoyable for all participants. Gentle slopes provide scenic views as runners navigate through the 1km or 5km routes tailored specifically for adult enthusiasts.
For younger ones, there are specially designed youth options available for those under 18 years old. The course layout includes notable features such as gentle inclines that offer breathtaking vistas, ensuring a memorable experience no matter which distance is chosen.
Since its inception in 2024, the Onesie Run has been supporting local animal welfare by raising funds and awareness for the Calgary Humane Society. This event isn't just about running; it's also about bringing joy to runners of all ages while fostering community spirit.
Race morning will see attendees feeling comfortable at -5°C despite slightly humid air conditions (69.8%). Steady winds around 10 km/h and a low UV index of 1.4 (low) make layering essential for managing temperature fluctuations effectively.
Registration is available online through https://raceroster.com/events/2026/115415/onesie-run, with fees set at CA$27.38 per adult and CA$21.03 for youth and children under 18 years old. Participants can pick up their bibs from Monday, November 6th to Friday, November 11th at Calgary's City Hall. Valid ID and proof of payment are required along with any specific items mentioned by organizers during registration.
With relaxed age requirements allowing anyone over 18 to join, this event is perfect for both newcomers and seasoned runners alike. Ensure you have your onesie ready and bring all necessary items as per instructions upon arrival.
This unique race isn't just about running in an unusual costume; it's a celebration of community spirit and support for local animal welfare initiatives. The Onesie Run promises to be a must-attend event for those who love animals or simply enjoy the fun of running in onesies with friends, family, and fellow participants.
