Sinister 7 Ultra is a grueling trail running race that takes participants through the rugged and remote terrain of Alberta's Rocky Mountains, featuring over 6,600m of elevation gain across its 100-mile course.
Official event pageWhat this race demands
Sinister 7 Ultra requires athletes to sustain forward progress across 161 kilometers and 6,692 meters of mountain elevation through the rugged terrain of the Alberta Rocky Mountains.
Massive Climbing Volume
Accumulating 6,692 meters of elevation gain over a 161-kilometer distance demands sustained muscular endurance and efficient climbing posture for steep, rugged mountain ascents.
Descending Durability
The extensive elevation changes require significant eccentric quadriceps strength to absorb the physical impact of prolonged downhill running over remote terrain.
Ultra-Distance Pacing
Covering a 100-mile mountain course requires strict physiological discipline to manage energy output and prevent premature muscular fatigue over many hours of continuous movement.
Given the substantial duration of a 161-kilometer mountain ultra, athletes should consume 60 to 90 grams of carbohydrates per hour to maintain stable glycogen levels.
