The Mount Robson Ultra Marathon will be an “out-and-back” run on the world famous Berg Lake Trail. The route passes through several different environmental zones and has its turn-around point just past the the shores of magnificent Berg Lake, truly making this marathon a one-of-a-kind experience. The route has been extended in 2015, to be 50 km long, an Ultra Marathon.

The ultra marathon has an elevation gain of 825m/2,700ft over the 25km to the turn-around point. The section from Whitehorn Campground to Emporer Falls Campground climbs steeply and almost continuously through the Valley of a Thousand Falls for about 5km, with an elevation gain of about 500m/1650ft. Most runners will find themselves walking much of this section.

The Berg Lake Trail is the most heavily used backcountry trail in the Canadian Rockies, with over 2,000 overnight users each year. The trail is very well maintained, and is mostly hardpacked ground with very few exposed roots or protruding rocks.
