Sarah Hammer
8-Time World Champion, 4-Time Olympic Medalist
The four-time Olympic medal winner, eight-time world champion and three-time Olympian who set two world records evolved from her initial focus as an individual and team pursuiter to develop the all-around skills required to become a world champion omnium rider. Now America’s most accomplished cyclist is transitioning into the role of coach, teacher and mentor to develop the next track cycling champions.
By winning her 15th UCI Track Cycling World Championships medal in April 2017, Sarah Hammer wrote one of the final chapters in the competitive career of the most prolific cyclist in U.S. history. The four-time Olympic medal winner, eight-time world champion and three-time Olympian who set two world records evolved from her initial focus as an individual and team pursuiter to develop the all-around skills required to become a world champion omnium rider. She adapted again to win her final world championships medal in the points race. Now, America’s most-accomplished cyclist is transitioning into the role of coach, teacher and mentor to develop the next track cycling champions.
Hammer began cycling at age eight when her father, Cliff, introduced her to the sport in their hometown of Temecula, California. She was a quick study and won her first junior national title in 1995. After rising up the ranks and competing for two years at the elite level while living at the Olympic Training Center in Colorado Springs, she quit cycling in 2003 citing burn out. Hammer sold most of her equipment, went back to school and worked various odd jobs. The story could have ended there, but thankfully fate intervened.
While watching her former teammates and competitors race on television during the 2004 Olympic Games, Hammer’s competitive flame was reignited. Reinvigorated, she hasn’t looked back since. Hammer ended an eleven-year drought for the USA when she won the world champion’s rainbow jersey in 2006. Along with winning seven more world championship titles, she won a pair of silver medals at each of the last two Olympic Games – 2016 in Rio and 2012 in London.
With her unparalleled cycling career winding down, Hammer has shifted her focus to sharing her wisdom and experience with athletes at Performance United, the high-performance cycling center based in Colorado Springs that she co-founded with her coach and husband, Andy Sparks.
