The Facebook post read “My mom just set a world record.”

Then, #mymomiscoolerthanme.

Another son just kept thinking “My mom is fricking nuts.”

Denise Mueller is crazy — in the best way. In the way where she just kept pushing her body and boundaries and mental blocks until she did what no woman has ever done.

The 43-year-old mother of three sons is the world’s fastest woman on a bicycle. Ever.

She set the women’s land-speed record for cycling when she rode 147.75 mph (not a typo) on the Bonneville Salt Flats in Utah last September.

“It’s so surreal out there. It’s being in the flow,” she said. “The world slows down and sort of becomes a warped sense of reality. It’s what I’m meant to do. Literally, there’s nothing else in the world but what I’m doing and time slows down.”

The Carlsbad, California resident is being honored at this year’s El Tour de Tucson. She will celebrate Southern Arizona’s largest participatory athletic event by riding in the 55-mile race on a tandem bike with her coach, John Howard.

Saturday’s race around the perimeter of Tucson is a twist for Mueller, who won the female division of the 75-mile race last year. It will be a training ride for her next pursuit — the overall land-speed record of 167 mph set by Dutch cyclist Fred Rompelberg in 1995.

“The faster I go, the slower everything else seems.”

The speed is what keeps her going, says her son Daniel Boever, 17. “She’s an adrenaline junkie. She loves speed.”

She drives Go Karts, rides off-road motorcycles, and races cars. She also races her modified zippy Mini Cooper through a timed course (called autocross).

5 questions with Mueller

• What is a land-speed record and how does it work? A cyclist is towed by a specialized car to 90 mph and then has to gain additional speed on her own as she drafts behind the pace car which is blocked from the wind by a fairing or a structure added to increase streamlining or reduce drag.

On a customized bike with an elongated frame and motorcycle wheels and tires to reduce the center of gravity, Mueller wears a special leather-and-lycra racing suit. Her helmet has a two-way radio that helps her communicate with the driver of the car.

• Where did this idea come from? Mueller was a 13-time junior national cycling champion when she decided to hang up the bike at age 19. She spent the next two decades raising her boys: Jonathan, 22, Michael, 21, and Daniel, and working in her family’s security business. She’s now CEO of Rancho Santa Fe Security.

She wedged in gym workouts when she could, ran some marathons and did a full Ironman triathlon in 2013. She crossed paths with Howard who floated the idea after encouraging her to do more training.

“You need to re-legitimize yourself in the cycling world so people understand who you are,” Mueller recalled Howard saying. “He saw something in me that I didn’t see.”

Howard, a three-time cycling Olympian himself, also set the land-speed record in 1985 (152.2 mph.)

Mueller won two master’s cycling titles and proved she was ready.

• What did you learn from parenting that helps in your athletic pursuits? Mueller’s says the athleticism and goal-setting are in her genes. Her mom jumped out of a plane on her 80th birthday, and her dad cycled around the perimeter of the U.S. (12,100 miles) in 9.5 months.

“I had parents go above and beyond, with no limitations for their kid,” she said.

With that as her foundation, Mueller found patience in more than 20 years of mothering.

“There’s a bigger reason for things. When you’re young, it’s hard to see the impact of things long-term. When you’re a parent, you’re an example.”

There were sacrifices, lots of training and she relishes showing the boys and others that hard work pays off.

• How do you train? Mueller rides about 150 miles a week between a couple of long rides with training group of consisting of mostly men and high-intensity work at the Velodrome in San Diego. Her gym workouts include intense strength work. She also rides behind a motorcycle (called motor-pacing) so that she can practice drafting at high speeds and pedaling at a high turnover rate (professional rider; do not try this at home).

• What’s next for you? Next September, Mueller aims to break the overall land-speed cycling mark of 167 mph held by Rompelberg.

“One hundred seventy mph is my ultimate goal,” she said. “We will have our special team back. I’ve enjoyed it every step of the way. It’s not scary or intimidating at all.

“We’re doing this again because we didn’t get to unleash the mph we knew we could accomplish.”
