Ultra Runners

Starting at 7:45AM, solo ultra-marathoners will complete the full 50KM distance on their own. The perfect beginner ultra, with the loop course you are never more than 5km from party area. Lots of access areas for your supporters to cheer you on!

ALL TEAMS are required to provide volunteer assistance with the running of this race:

  • All teams will provide one volunteer per team who will be given a choice of locations / times at which to volunteer, or will be assigned where needed.
  • Volunteers can be team members running an early or late leg, and assigned to a corresponding late or early volunteer position.
  • You must complete your Volunteer Registration for your team’s registration to be considered complete.
  • Volunteers must be 16 years of age or older.
  • A volunteer cannot volunteer for more than one team (teams cannot “share” a volunteer).
  • The easiest way to sign up your team’s volunteer is to provide their information during your team registration.
  • If you’ve already registered your team and need to add (or update) your volunteer information, go to your Trackie account and login with the email and password you provided during registration. You should see “Whistler 50 Relay Team Entries” come up. To the left of this, click on “Manage” and “Edit Entries”. On the next page, click the “Volunteer Info” to register/update your team’s volunteer.

While each team is required to provide one volunteer, we also welcome additional individuals who can assist for a few hours!

If you or someone you know wishes to volunteer (on their own, not as part of a team), please sign up here and someone will be in contact closer to race weekend. You will receive a race souvenir, an invitation to the post-race party, and the eternal gratitude of the race organizers!

Are you marshalling on course and want to see where you’ll be? If you’ve already been assigned your location, find it on this map. If you signed up to volunteer and haven’t heard from us at least one week before the event, please email
