Sarissa was inspired by her father to make her first steps into the world of triathlon. She did her first triathlon at the age of 13 and became hooked. In 2007 she moved to Sittard to become a full time professional triathlete with the aim to qualify for the Olympics. Highlights during her years at the National Triathlon Training Center include a second place at the U23 World Championships and winning the European Cup in Genève.
In 2015 Sarissa made her long-distance debut by placing second at the inaugural Ironman Maastricht. Other notable results include winning Challenge Riccione (2021) and Challenge Gdansk (2021). She crowned this successful year by becoming the first female Dutch long distance World Champion in a new national record (08:32:03).
