Calum started running at the age of four years old at the 1988 Cajun Cup 1km. Originally born in Aberdeen, Scotland to Canadian parents, Calum grew up all over the world, living in England, Thailand, Australia, and back-and-forth between the USA and Canada. He now resides in Houston, Texas.
His wife, Julie, and three girls, Alessandra, Holland, and Maya, have helped define Calum’s running career after a series of Guinness World Records pushing his daughters in the stroller. He is a diverse runner, competing in all distances on all terrains in a single year, from speed on the track to grueling ultras in the mountains and everything in-between.
Calum has also been coaching for over 15 years and operates his own training programs online and locally through Hardloop Endurance.
