About the race

The Mount Robson Marathon is a grassroots, community-oriented trail running event held on the Berg Lake Trail within Mount Robson Provincial Park in British Columbia. The event features multiple out-and-back running distances that start at the Mount Robson Welcome Centre and follow the Robson River. All race courses have water and aid stations along the route.

Distances offered include:

  • Ultra Marathon observes the entire Berg Lake Trail and reaches Berg Lake.
  • Half Marathon follows a mostly well groomed double-track past Kinney Lake to gravel flats above the lake.
  • Kinney Lake 12 km turns around at the Kinney Lake outflow bridge.
  • Flatlander 5 km is mostly flat open road with a short wide, gently inclining trail section at the Berg Lake Trail start.

The Ultra Marathon includes 825 m of elevation gain, with most climbing occurring in a 5 km section called the Valley of a Thousand Falls. Runners pass through several different environmental zones along the Berg Lake Trail. A free Kids’ Fun Run takes place around the Mount Robson Information Centre during the day.

Registration opens January 31 and updates about the event are posted on the event online channels. The event is organized as a community activity with listed local sponsors supporting logistics and services. Visit the organization's website for the most recent information.
