Mary is the founder and head coach of LYNX Triathlon. She has been swimming her entire life – as a competitive age group swimmer, as a member of an NCAA University team and as a triathlete. She tackled her first Sprint tri in 2002. A decade later, after she completed an IRONMAN, she became an NCCP Certified Triathlon Coach. LYNX Triathlon was born from her desire to share her passion for the sport with others.

While focusing on triathlon coaching, she realized that swimming was often a weakness and limiter for triathletes. She decided to return to her swimming roots and studied to become the 2nd Swim Smooth Certified Coach in Canada. This training honed her ability to help any swimmer – from beginners learning how to swim to veterans looking to develop better technique, efficiency and speed.

She is excited to be involved with the Terminator Foundation and is looking forward to helping athletes of all abilities reach their swimming goals. LYNX Triathlon is a valued sponsor of the Terminator’s triathlon program.


Vanisha Breault is the Founder of the Terminator Foundation and Tri Terminator. Vanisha launched the Tri Terminator program in 2016 after the completion of her own first 70.3 Ironman. With just 3.5 months of training and with no prior triathlon experience, Vanisha found the training challenged her physically and mentally beyond what she had imagined she could achieve.

Vanisha had been an avid runner and running coach for over a decade. For the longest time running had been a go-to for her mental health and recovery, but the triathlon experience transformed her thinking and blew the lid off her own limitation.

Being in long-term recovery from alcoholism and being in one of the darkest periods of her life watching her own daughter battle addiction on the streets, Vanisha found training for the half ironman paralleled the fight to overcome addiction and depression.

And so, the dream of bringing others through this same journey to recovery was born in her heart and in the fall of 2016, plans were made to launch what today is known as: Tri Terminator. In 2017, Vanisha went on to complete her training and became a NCCP Certified Triathlon Trainer. With years of experience working within the realm of addiction/mental health from the front lines, business & community engagement to counselling/coaching, Vanisha believes that the physical component of exercise is one of the most vital keys to ensuring success in overcoming addiction and mental health issues.

“The truth is you can recover, it’s not just a tag line; it’s a fact.” –Vanisha
