The middle of seven children (five girls and two boys) from London, Ontario, Canada, her first sport was ice skating.

In elementary school she ran as part of her curriculum and as a great way to cross train for figure skating.

Marchant decided to quit skating the following holiday season and joined The London Western Track and Field Club.

Marchant kept up her running throughout high school, racing at track meets, and regional championships, eventually earning a scholarship to the University of Tennessee at Chattanooga.

With a hefty work load, and ever increasing mileage, she has claimed "the tenacity I draw on to run marathons was forged during this time".

Marchant placed fourth in the women's marathon event at the 2014 Commonwealth Games, in Glasgow, Scotland, with a time of 2:31:14.
