Jarrett, a two-time Olympian, is departing to open a sports training centre in his hometown of Heber City in Utah.

He was a US Ski Team athlete from 1992 to 1998, competing in two Olympic Games and three World Championships.

Retiring from competition in 1998, Jarrett spent several years coaching cross-country skiing at the University of Colorado.

Jarrett then joined the US Ski Team in 2002 as the World Cup B coach, before being named as head coach in 2008.

The American team produced its best ever results during his tenure, including the country's first Olympic medals in Nordic Combined at Vancouver 2010.

The team won four medals in the Canadian city, including gold from Bill Demong in the large hill/10 kilometres event.

Jarrett was named United States Ski and Snowboard Association (USSA) Nordic Combined Coach of the Year four times and USSA international overall Coach of the Year in 2010.

"I really enjoyed it," he said.

"I liked seeing progress.

"I liked seeing the athletes come to training motivated every day."

The focus of Jarrett's new training centre will be on speed and agility for those "looking to make gains and improvements in their specific sports".

The programmes will be designed for all athletes, all levels, all ages and all genders.

The new centre is expected to open this summer.

An announcement on the American coaching set-up is due to be made in the near future.
