Denise Mueller-Korenek smashes a 23-year-old world record, riding 183.932 miles per hour pacing behind a dragster.

On the Bonneville Salt Flats, tucked in behind a 1,000-horsepower drag race car, Denise Mueller-Korenek hit 183.932 miles per hour, smashing a 23-year-old world record.

“It was a crazy wild ride to 183.9 mph, but so worth the sacrifice and years of focus on becoming the fastest human on a bicycle in the world,” said Mueller-Korenek after breaking the record on September 16.

She hit the record speed on her second attempt, breaking Fred Rompelberg’s 1995 Paced Bicycle Speed Record, 167mph.

Mueller-Korenek, 45, is familiar to top speeds on Utah’s salt flats. She previously set a women’s world record of 147.75mph in 2016. This Sunday, the mother of two took the world record outright, paced by an overhauled version of the dragster that paced Rompelberg to his record speed.

“For the first time pacing for Denise I drove outside of my comfort zone to get the job done. Every second of the day I’m a tad anxious but when Denise and I leave the starting line all my nerves calm,” said Shea Holbrook, who drove the dragster.

“This is the most intense thing I’ve ever done for obvious reasons [having responsibility for someone else] but you know what crazy? I’d do it again. We made history at the Bonneville Salt Flats and it’s a day I’ll never forget.”
