Overlander Sports Half Marathon
Race Day Weather
Comfortable temps, big temp swing
Mild 59°F temps at gun time mean comfortable early miles without overheating risk. Temps will climb significantly to 75°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing. Moderate humidity at 70% is worth noting for effort level, especially in later miles.

Race Info
The Half Marathon covers 21.1 km on a single loop of western Yellowknife, starting and finishing at Overlander Sports. The official 2026 map shows the route circling the old airport lands, with three aid stations on the loop and a turnaround point on a short spur near the start and finish. The marathon runs the same loop twice.
