Denise Mueller-Korenek (born c. 1973) is an American cyclist. As of September 2018,[update] she holds the world record for paced bicycle land speed[1][2] and is considered "the fastest cyclist on earth".[3][4] She set the record on September 16, 2018, at the Bonneville Salt Flats in Utah, by traveling an average of 183.932 mph (296.009 km/h) on a custom-built carbon KHS bicycle behind a custom-built vehicle to minimize air resistance.[5] The previous record, 167 miles per hour (269 km/h), was set in 1995 by Dutchman Fred Rompelberg. Two years earlier she set the women's bicycle land speed record, pedaling 147.7 mph (237.7 km/h).[6] She is the first and only woman in history to hold the world record, which was first established in 1899.[7][8]
