Jamie Staff leads USA Cycling’s BMX Racing and Freestyle programs. Born in Ashford, Kent, England, Jamie raced BMX for 20 years winning the World Championships in 1996. In 2001, he turned to Track racing in the pursuit of the Olympic Games. His transition appeared to be seamless qualifying for Team Great Britain's sprint program in his first attempt. At the Commonwealth Games, he rode to silver in the Team Sprint, broke the National 200m Record, and rode to bronze in the Kilometer. Less than a year into track racing, he helped Team GB win gold in the Team Sprint at the 2002 UCI Track World Championships. In 2004, he became the Keirin World Champion and punched his ticket to the Athens 2004 Olympic Games. It wasn't until the next Olympics that Staff would walk away with a medal. Not only did he win several medals in the World Championship and Commonwealth Games in the next four years, but he would win gold in the Team Sprint trio and break the World Record at the Beijing 2008 Olympic Games.

After 7 years on the track, he turned to coaching. At the Rio 2016 Olympic Games, under Staff's direction, USA Cycling’s BMX program won its first gold medal, a silver medal, and recorded two fourth place finishes. With the introduction of BMX Freestyle to the Tokyo 2020 Olympic schedule, Staff took over that program. BMX Freestyle won its first medal in the sports debut with silver.

Arielle Verhaaren is one of the most successful American BMX racers and was the first American woman to win a UCI BMX Supercross World Cup.

Having started her BMX racing career at the age of five, she won multiple national titles as an amateur before turning pro at the age of 15. While juggling her professional racing career with a college education, she was selected as an alternate to the 2008 Olympic Team and the same year won the overall UCI World Cup series. In 2009 she won a bronze medal at the UCI World Championships and in 2011 she became the first American woman to win a UCI BMX Supercross World Cup, a feat she followed up with a Pan American Games silver medal. In 2012, Arielle was the first athlete selected to the London Olympic BMX Team but a training accident the day prior to departure left her cheering for her teammates from the hospital. She returned to the World Cup circuit in 2013 and ended the season ranked second overall before officially retiring.

Arielle holds a BS in Exercise Science from Brigham Young University and has completed her MBA from Devry. She spends her free time chasing her daughter, coaching the future generation of BMX athletes, and sneaking in rides and races whenever possible.

A successful professional cyclist in his own right, Jim coached several cyclists on the side and eventually retired from racing in 1999 to focus solely on his flourishing coaching career. After developing several notable cyclists, he originally came to USA Cycling to run the women’s road program in 2002. After earning Coach of the Year distinctions from the U.S. Olympic & Paralympic Committee in 2003 & 2004, Jim was promoted to director of endurance programs, overseeing the development of American junior, U23, and women endurance athletes in road and track cycling. After making significant strides toward the USA Cycling National Development Program’s goal of developing the next generation of American cyclists, he was named Vice President of Athletics in 2010. In 2017 Jim left USA Cycling to become the Vice President of Business Development for Training Peaks. Unable to resist the Olympic call, he returned to USA Cycling in 2020 as the Chief of Sport Performance.

In his spare time, Jim also provides day-to-day training programs for athletes such as 2018 Mountain Bike XCO World Champion Kate Courtney and international stars like Chloé Dygert and Christopher Blevins. He has earned the International Olympic Committee’s highest honor for coaches, the Order of Ikkos, three times, all for coaching 3-time Olympic Champion Kristen Armstrong to victory.

A native of Casper, Wyo., Jim also earned a Bachelor’s degree in exercise physiology from Colorado State University. Miller resides in Colorado Springs, Colo., with his wife and two children.
