Mark is a co-founder and coach at ONE80 Endurance and remains an elite age-group multi-sport athlete, actively racing throughout the year alongside coaching his athletes. His continued involvement in competition allows him to stay closely connected to the demands, pressures, and realities faced by endurance athletes at every level.
Mark began his triathlon journey in 2010, drawn to the sport by the challenge of mastering multiple disciplines. As a dedicated amateur sportsman, he works hard to balance a full-time role at an investment bank, family life, and a demanding training schedule, often relying on early mornings and late nights to get the work done. This balance has shaped his coaching approach and given him a deep appreciation for the commitment required to perform while managing real-world responsibilities.
He believes the most important attributes of a successful athlete are dedication, a genuine love for the sport, and a strong, positive mindset. In a sport that tests athletes across three disciplines, Mark understands that success often requires the ability to push through discomfort and “open the hurt locker” in order to reach the finish line.
Mark travels and races internationally and brings a wealth of experience in training, travel logistics, and racing abroad to the ONE80 team.
Career highlights include:
10 × Ironman victories
10 × Ironman 70.3 victories
World Record Ironman Age Group overall time (2017)
