About the event

Racing Dusk 20 Miler
Iron Legs Running Company introduces the Racing Dusk 20 Miler, an innovative race set near the winter solstice. This unique event unfolds at West Bragg Creek, where participants navigate three distinct loops totaling 20 miles. Unlike traditional races, competitors have the freedom to choose their loop sequence—whether that means tackling the shortest and flattest route first or starting with a challenging climb. Each loop must be run counterclockwise, adding an element of unpredictability as runners may not know where others are on the course at any given moment.
The race takes place under the winter sky when daylight is scarce, creating a dynamic challenge for participants. With a time limit of 8 hours, racers need to balance their pacing against unpredictable weather conditions such as cold temperatures and snowfall. As dusk falls around 4:30 PM during this season, runners must strategize wisely to complete all three loops before night fully descends.
This event offers an immersive experience in the serene winter landscape of West Bragg Creek, where each loop presents its own unique terrain and elevation changes. The combination of strategic planning, physical endurance, and environmental challenges makes the Racing Dusk 20 Miler a thrilling addition to any runner's calendar.

Scenic view of

Calgary is Alberta's largest city and Canada's third-largest, and is near where the prairies end and the foothills begin. That makes it the eastern gateway to the Rocky Mountains and an important centre of trade and tourism for the western prairies. It is your best point of access for Banff and Jasper, and a worthwhile destination in its own right. Calgary is the heart of the largest metropolitan area between Toronto and Vancouver, with over 1.3 million people as of 2021, making it Canada's fifth largest metropolitan area. Nicknames of Calgary include The Stampede City and YYC.
