Denise Mueller-Korenek has become the fastest person on a bicycle. On Sunday she was clocked at 183.9 mph on the Bonneville Salt Flats in Utah. Mueller-Korenek, 45, shattered the existing motor-paced cycling land speed record of 166.9 mph previously held by Dutch cyclist Fred Rompelberg in 1995.

She was towed behind a dragster driven by Shea Holbrook until reaching 150 mph at the two-mile mark of the five-mile salt flats course, according to the Wall Street Journal. Mueller-Korenek then released a cable and pedaled under her own power behind the dragster’s “slipstream”.

“I’m speechless,” Mueller-Korenek told the Journal. “It hasn’t hit me yet.”
