BOISE, Idaho (KTVB) -- Two-time Olympic gold medalist Kristin Armstrong just can't stay away. The cycling champion announced Tuesday that she is ending her retirement and returning to professional racing.

"After retiring in 2012, I have been thrilled to see the recent growth of women's races not only in the United States but all over the world," Armstrong wrote in the announcement on her website. "It is fantastic that top-level races are giving an opportunity for women to showcase their abilities and talent and the current momentum in the sport is undeniable."

Armstrong says she hopes her return will bolster that development. And she's wasting no time: The Olympian's first race is scheduled for May 7 in Mexico. She will compete in the Pan American Continental Time Trial Championships in Morelia, Michoacán. Armstrong took top honors in the 2008 Olympic Games. She won gold again in 2012 before retiring later that year and taking a job with St. Luke's Medical Center in Boise.
