Editor’s Note: This blog was originally written in 2019, but we keep updating it with the latest race events. Last updated, January 16, 2024.

You may know that Whistler is a world-class ski resort, but did you know it’s also a runner’s paradise?

With a wide variety of trails that cater to everyone from recreational runners to pros, Whistler’s fresh air and outdoor vibes are undeniably good for the heart and soul. My personal favourites are the paved Whistler Valley Trail network and the gravel trails that circle Lost Lake. While my deer-in-headlights depth perception forces me to tiptoe carefully through the rocky terrain of the Coast Mountains, our high alpine trails are loved by many locals.

Whistler hosts several local and international running events, the 2024 running calendar is packed with unique events that cater to various abilities and interests. The sheer number of events can make picking one feel like a daunting task, so we’re here to help with this handy guide:

Whistler Half Marathon presented by Smartwool

The Whistler Half Marathon is one of Canada’s most scenic, all-natural runs and a personal favourite of mine. There are five distances to choose from ranging from 1 kilometre to 30 kilometres (including a 21-kilometre half marathon, of course), making it welcoming for all levels. The course is now all trail-based and starts and ends in Olympic Plaza, with the majority of the race around Lost Lake Park.   

They’ve updated their divisions to reflect the fact that not every athlete exists within the traditional, binary divisions, and the new Beyond the Podium Awards are aimed at redefining how we think about success with awards for Super Parent, Closest to Goal Time and Top Fundraiser.

Don’t want to run? You can walk or opt to be an official cheer squad member, and make sure you head to Whistler Olympic Plaza to celebrate afterward.

The call of the mountains brought this mix of city / country girl to Whistler over 5 years ago. Tina is spontaneous but overly plans, outdoorsy but has no problem hiding in a shopping mall, outgoing but enjoys the quiet peace of reading a novel. She is genuinely curious and will often find out a person's life story over a pint of beer.
