Career
Rieder trains under Polish-born head coach and four-time Olympian Krzysztof Kucharczyk for the national team, while shooting at Bubikon Pistol Shooting Range (German: Pistolschützen Bubikon) on the outskirts of her hometown Rüti. Rieder qualified for the Swiss squad in pistol shooting at the 2004 Summer Olympics in Athens. Two days later, Rieder recompensed her bitter air pistol feat to shoot a brilliant 293 in precision and a lowly 275 in the rapid fire stage for a tally of 568 points in the 25 m pistol, but her results were good enough to put her in twenty-ninth position out of thirty-seven shooters.
