City insight: Calgary
Calgary is the largest city in Alberta, Canada, sitting where the Bow and Elbow rivers meet in the southwestern part of the province, about 280 km south of Edmonton. The city proper had 1,306,784 residents in 2021, making it the third-largest city in Canada. The climate is cold, dry and windy with chinook winds, so late spring, summer and early autumn are the best seasons to race.
