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

Our next & upcoming Onesie Run is scheduled for Saturday, November 15th, 2025.

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 medallion and ribbon.

Fastest 1st, 2nd and 3rd place rankings for the 1km (kids) and 5km (all ages) receive special prizes and mentions.

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!

Each registrant is automatically entered into giveaway draws for various awesome prizes. Examples of previous giveaways include $50-$100 Sport Chek, Spolumbo's, etc. Giftcards and prizes are distributed once the 5km route is completed.
