Ashton Lambie (born December 12, 1990) is an American track cyclist known for being the first person to complete an individual pursuit in under 4 minutes, and for his moustache.
Lambie was born in Lincoln, Nebraska. He is of partial Moravian and Czech descent and is a distant relative of Dale M. Cochran.
Lambie races on gravel in Kansas. In October 2015, he set the World Ultracycling Association record for cycling across his home state of Kansas from West to East. This record was surpassed a few months later in May 2016. In his debut at the Track National Championship, Lambie won the Individual Pursuit, and finished second in the omnium and points race. This earned Lambie a spot on Team USA. His first race with Team USA was the 2017 Pan-American Championships.
Lambie is a partner of racing cyclist and NASA astronaut candidate Christina Birch.
