Mark Arendz enters the 2014 Sochi Paralympics as the reigning World Cup biathlon champion and the world champion in the 7.5 km biathlon sprint.

He was a member of the Vancouver 2010 Paralympic team and has continued to rise in the international standings ever since. He produced a breakthrough season in 2010-11, ranking second overall in the IPC World Cup standings collecting three gold, two silver and a bronze. He showed in 2011-2012 that season was no fluke, earning two gold, two silver and two bronze on the World Cup, which again ranked him second overall.

In 2012-13, Arendz captured his first career IPC Biathlon World Cup Crystal Globe. He earned four podium finishes on the circuit, in addition to racking up three World Championship medals including his first victory at the worlds.

Arendz lost his left arm above the elbow in a farming accident at age seven while attempting to put corn into a grain auger and losing his balance. After his accident he worked for the War Amps organization as a junior counsellor, using his experiences to teach others about farm safety. While the accident was initially a major shock, it did not deter him from pursuing his love for sport and competition.

In 2012, Arendz was one of three finalists in the Bell Aliant Senior Male Athlete of the Year award for Prince Edward Island athletes. He achieved the Duke of Edinburgh Gold Award by the time he turned age 17. He is enrolled in human movement studies at the University of Calgary.
