Brooke Miller (born March 21, 1976)[1] is an American former professional road racing cyclist and U.S. national team member.

She graduated with a PhD in Evolutionary Biology from the University of California, Santa Cruz in spring 2007,[4] and began racing full-time in 2008, although she does work as a software developer in her spare time.

Miller won the first women's criterium to be held alongside the men's Tour of California, the race was sponsored by the Redwood Regional Breast Center.

However, she retired from the sport in August 2010 following the Chris Thater Memorial Classic, the official end of the women's NRC calendar.

[7] Miller cited difficulty living away from home in Europe and not wanting to make the sacrifices necessary to secure her spot on the 2012 Olympic team as the main reasons behind her retirement.
