Henzi later represented her nation Switzerland, as a 38-year-old senior, at the 2008 Summer Olympics, and also rode professionally for more than five seasons on Fischer-BMC Team, before retiring from the sport in early 2010.

As a full-time member of Fischer-BMC team since her professional cycling debut in 2002, Henzi sought sporting headlines on the international scene at the 2005 UCI Mountain Bike World Championships in Livigno, Italy, where she claimed the bronze medal in the women's marathon race, adding the Swiss national championship title to her career resume in that same year.

[6][7][8] Shortly after the Olympics, Henzi established herself again as the top female cyclist by surpassing her teammate Esther Süss for another gold medal at the second and final stage of the Nissan UCI MTB World Cup in Ornans, France.

[9] Because of her continuous triumphs and a more profound dedication to the sport, Henzi was officially nominated to be the Swiss Sportswoman of the Year, but did not reach the final shortlist.

[10] At the 2009 UCI World Championships in Graz, Austria, Henzi could not match a sterling ride with a bronze-medal effort in the women's cross-country race, trailing behind her rivals Spitz and Süss by almost three minutes.
