Klondike Ultra and supporting races
This event is a series of trail races that use varied terrain and repeat sections. Distances offered include:
- 6 km Klondike Dash
- 10 km Klondike Rush
- 27 km The Dead Horse
- 50 km Little Klondike
- 100 km Klondike Ultra
Courses start on Wierenga flats and move onto single track and old wagon trails. Routes include sandy climbs and descents, stretches alongside the Athabasca River, moss covered sand dunes, and boreal forest single track. Some sections run beside old growth cottonwoods and birch and alternate between wide open fields and narrow trails.
The Klondike Dash begins on a wide field for a few hundred metres, then climbs via single track and returns on the same route with a finish in front of spectators. The Klondike Rush features a short flat section on Wierenga flats, a valley-side single track climb and a sandy old wagon road before more single track. The Dead Horse follows Wierenga flats, climbs up river to a sandy ascent into moss covered dunes and then into boreal single track. The 50 km and 100 km starts are in the valley bottom and quickly climb onto an old wagon trail lined with cottonwoods and birch. Visit the organization's website for the most recent information.
