In-Person Race


Established in 1978, the Under Armour Spring Run-Off is an event steeped in tradition. As the annual kick-off of the Canada Running Series, this event celebrates the return of spring in Toronto’s beautiful High Park, welcoming runners of all ages to participate. And this year, we’re celebrating 45 years of running in High Park!

With a focus on family-friendly fitness, you can choose from 8 km, 5 km, and Kids Run  distances and can complete your race in-person or virtually.  New this year, the Thaw-Out Thirteen  gives participants the option to complete a Virtual 5 km run as part of their training for the In-Person 8 km race. Participants of the Thaw-Out Thirteen will also receive a bonus UA swag item, UA Storm Run Liner Gloves! Featuring designs inspired by the nature and wildlife in High Park, participants in all distances will receive an Under Armour technical shirt and finisher medal.

Under Armour  will be providing an awesome training plan to help you reach your distance goal, while having some fun along the way. We promise to keep you motivated throughout the cold winter months with tips, training and content from our ambassadors and race partners.

It won’t be a walk in the park, but we’re excited to help you say goodbye to winter and say hello to spring  with the Under Armour Spring Run-Off

Kill The Hill Challenge

Who are the best hill runners in Canada Running Series? Who will be crowned King and Queen of the Hill at this year’s Under Armour Spring Run Off? For over 40 years, runners have been conquering High Park’s Spring Road Hill in the final 365 metres of the Spring Run-Off. This year we want you to ‘Kill the Hill’ and give it everything you’ve got in those last 365m as part of our Kill The Hill Challenge!

Back by popular demand, we will be offering a separate, complete set of race results for that 365m section up the legendary hill. For both 8K and 5K you’ll be able to compare your hill-running strength against Canadian Running stars, as well as your club and crew friends.

Times will be calculated via Sportstats Race Results timing mats in the final 365m of the race and prizes will be awarded to the top male and female in both the 8K and 5K distances, including on-stage photo opportunity with cape and crown! Visit the Sportstats booth in the party site after the race to see if you’re in the running to win. Winners will be announced during our Awards Ceremony beginning at 11:50 a.m.

We want to know who’s got the most pep left in their step as they make their way up Spring Road Hill, carried by the deafening cheers of spectators, family and friends, to the finish line.

Everyone who registers for the Under Armour Spring Run-Off will be automatically entered into the challenge.

Bonus Item For Thaw-Out Thirteen

Like a baselayer for your hands. The Men’s UA Storm Run Liner Gloves are form-fitting, light and stretchy, with the right warmth when it’s cool out—or wear them underneath heavier gloves when temps really plunge. For a women’s fit, we recommend sizing down.
