We are both Calgary's - and Canada's - only official, dedicated Onesie Run!​

Our 10th Anniversary event is Saturday, November 14th, 2026. Nice, cool fall weather so that you don't overheat in your onesie. We carefully consider weather elements for all events! 

The 1km and 5m routes are great for all fitness levels. Participants may choose to walk, jog or run the event. Located in East Village, Calgary.

Fido-friendly, dogs VERY welcome! Leash responsibly, thanks!

Onesie Run raises awareness and funds for the Calgary Humane Society.
