Event Update for 2025:

The Mount Robson Marathon event, including the 50km Ultra, is back for 2025! We will be offering four options for runners to participate in the 50km Ultra, Half Marathon, Kinney Lake 12km and Flatlander 5km runs.

In 2021 the Berg Lake Trail sustained significant damage after an unprecedented flooding event. With several bridges missing, much of the trail being in a state that is unsafe for the public, and the likelihood of the Robson River changing course, the trail has been closed to the public for repairs. It re-opens this summer, and we are excited to once again have access to the full 50km Ultra Marathon route! 

We are very excited to once again be able to host running events on the Berg Lake Trail! The 50km Ultra, Half Marathon, Kinney Lake 12km, and Flatlander 5km will take place on Saturday September 6th, 2025. Registration will be available on our website starting on May 1st. Stay tuned to our website and Facebook page for updates.

The Berg Lake Trail is a world class hiking destination within Mount Robson Provincial Park. All of our running events start at the Mount Robson Info Centre and follow the Berg Lake Trail up the Robson River. The Ultra Marathon, takes runners up the trail past Kinney Lake, Whitehorn, Emperor Falls, Berg Lake and to a turnaround point at Robson Pass. The Half Marathon takes runners past Kinney Lake to a turnaround on Kinney Lake Flats. The Kinney Lake 12km run takes runners to a turnaround point at the outflow bridge at Kinney Lake. The Flatlander 5km is mostly flat open road with a small section of wide gently inclining trail at the start of the Berg Lake Trail. All of the runs are out-and-back routes with water/aid stations along the way. There is also a free Kids’ Fun Run around the Mount Robson Info Centre during the day.
