Marc Evans has been inspiring excellence in endurance athletes and coaches since debuting as triathlon's first professional coach in 1981. Triathletes in Motion, his fourth book, is his most comprehensive work to date and establishes a new standard for coaches and athletes with the Evans assessment principle by stressing the most important precept of coaching: individualization.

Marc has developed more than 100 hours of credential-based coursework on movement and stability and 75 hours on technique. He is a respected resource for elite coaches and conducts movement assessment workshops and masters-level education clinics. Marc also has lectured at sport science conferences around the world.

A two-time head coach for USA Triathlon, Marc led the elite 12-member team at the first World Championships in 1989 when Mark Allen won the gold medal for the United States. He was the head coach for the USA Triathlon performance testing at the Olympic Training Center and a founding member of USAT Coaching Commission. Additionally, he was the sports medicine conference coordinator and the director of endurance sports for the Ironman Sports and Endurance Center.

Marc is also the inventor and co-holder of the patent for the Speedo Contoured and Speedo Swim Foil training paddles that have set the standard in swimming design for over a decade. He was presented with the Award of Excellence from the American Medical Association triathlon division and was named the International Coach of the Year.

Marc lives in Boulder County, Colorado.

Jane Cappaert, PhD, is a leading expert in the field of biomechanics. Cappaert began her career at the U.S. Olympic Training Center in Colorado Springs, Colorado. She initially analyzed the biomechanics of athletes competing in a variety of sports. She then spent nine years studying and improving the technique of swimmers and triathletes while working at USA Swimming.

From 1997 to 2000, Cappaert designed, developed, tested, and patented Speedo International's first full-body swimsuit called FastSkin. During its debut at the 2000 Olympics in Sydney, swimmers wearing FastSkin suits won 83 percent of Olympic medals.

After the 2000 Olympics, Cappaert took a position at Reebok International, where she led a team of engineers at Reebok's Human Performance Engineering Lab. While at Reebok, she engineered athletic shoes to meet the specific functional and biomechanical demands of running, power motions, cutting motions, and jumping.
