We are both Calgary's - and Canada's - only official, dedicated Onesie Run!
Onesie Run is scheduled for Saturday, November 14th, 2026.
Nice and cool fall weather so that you don't overheat in your onesie. We carefully consider weather elements for all events!
The 1km and 5km routes are great for all fitness levels. Participants may choose to walk, jog or run the event. Youth and children (18 and under) tickets are budget friendly.
All participants receive a BIB, finisher MEDAL and a SWAG BAG! There will also be a RAFFLE - automatically included for all participants - for various prizes at the end! Previous giveaways have included gift cards to Great White Car Wash, Spolumbo's Deli, Sport Check and Phil & Sebastian Coffee. Other raffle prizes have included yoga mats, stress balls, sports pickle juice, and much more!
Fastest 1st, 2nd and 3rd place rankings for the 1km (kids) and 5km (all ages) receive special prizes and mentions.
Top 3x fundraisers receive special mentions, photo with event organizers, and surprise gifts.
Stick around once you cross the finish line! Cozy wood burning fire pits to warm your fingers, vendors with fun tents (and free stuff!), DJ to pump up the vibes, food truck for your cravings, and our charity partner onsite!
Onesie Run raises both public awareness and funds for the Calgary Humane Society. If you love animals, register for this amazing event. Throw on your onesie, stretch your legs and make a positive impact for the Humane Society!
Fur-friends VERY welcome - please leash responsibly!
See you on the big day!
