Provisional team rosters for the 2014 USA Pro Challenge have been confirmed and are headlined by Pro Challenge defending champion and fifth-place finisher in last month's Tour de France Tejay van Garderen, as well as 2014 Tour de France KOM Jersey winner Rafał Majka and teammate and Tour de France stage winner Michael Rogers.

The USA Pro Challenge will take place August 18-24 and will travel through ten host cities during its scenic tour of the Colorado Rockies. Highlights of the testing 550-mile route include the race's first-ever mountain finish at Monarch Mountain. Total elevation gain for the week will be a shade under 40,000 feet with a high point of 11,542 feet on top of Hosier Pass near Breckenridge. Other prominent mountain crossings include McClure Pass south of Carbondale, and Kebler Pass west of Crested Butte. See the full route here.

"I'm really looking forward to defending my race title in Colorado this year," said van Garderen, an Aspen, Colo., resident. "Because it starts in my hometown, it's different and more relaxed. To race in front of my family and friends is always special. We are bringing a really motivated team and with a summit finish this year, it promises to be another hard race."

Fresh on the heels of the Tour de France, many of the riders are in top form and will be strong competitors in the Pro Challenge. Three riders competing in the 2014 Pro Challenge finished in the top-12 places at the 2014 Tour de France, including van Garderen in fifth, Leopold König in seventh and Frank Schleck in 12th.

Majka, who took the KOM Jersey at this year's Tour and also won two stages, will be racing in Colorado. Additionally, the race also will feature two riders that finished on the podium in previous years of the Tour de France - Ivan Basso, who also is a two-time Giro d'Italia winner, and Schleck - and multiple riders who captured a stage win - Jens Voigt, Basso, Schleck, Rogers and Majka.

In what is being dubbed as his "Farewell Tour," fan favorite Voigt will compete in his last professional race during the 2014 Pro Challenge. Best known for his attacking skills and positive, fun-loving attitude, Voigt's professional cycling career has spanned 17 years and has been punctuated by many incredible performances and victories.

"I chose the Pro Challenge as my final race because of the fans," said Voigt. "All the fans in Colorado love outdoor activities, so they are all experts…they know exactly how hard it is to go up those crazy-long climbs. It's a beautiful state and I just always love the warm welcome and the support I get from the fans."

The elite professional roster of teams, which includes 128 riders from 30 countries, is comprised of six teams that competed in the Tour de France. Following is the preliminary complete list of riders that are currently confirmed to compete in the 2014 USA Pro Challenge.
