Acevedo and van Garderen crossed the finish line together.

The Queen Stage of the 2013 USA Pro Challenge presented the riders with a challenging day that included five climbs and ended in a downpour of rain. In a show of strength, Columbian climber Janier Alexis Acevedo of Jamis-Hagens Berman p/b Sutter Home powered up the road to Beaver Creek to take the stage win. Following just behind was Tejay van Garderen (USA) of BMC Racing Team who will now wear yellow heading into Friday's individual time trial in Vail. Van Garderen has a 40 second lead over his main GC rival, Garmin-Sharp rider Tom Danielson.

Stage 4 began today in Steamboat Springs with a neutral start that was cheered on by large crowds of spectators lining the streets. Racing kicked into high gear jumping to speeds of 40 mph at the official race start on the edge of town. As with the other days of the race thus far, attacks started coming from the get-go. An initial attempt from Tour de France champions Chris Froome (GBR) of Sky Procycling (2013) and Andy Schleck (LUX) of RadioShack Leopard Trek (2010) was unsuccessful and was reeled back in within a few minutes.

Shortly after, a group of nine riders pulled away. As some were dropped and others joined, the group got situated to include Timmy Duggan (USA) and Mick Rogers (AUS) of Team Saxo-Tinkoff, Danny Pate and (USA) Kanstantsin Siutsou (BLR) of Sky Procycling, Tony Gallopin (FRA) of RadioShack Leopard Trek, Lawrence Warbasse (USA) of BMC Racing Team, Davide Villella (ITA) of Cannondale Pro Cycling, Matt Cooke (USA) of Jamis-Hagens Berman p/b Sutter Home, and Serghei Tvetcov (MDA) of Jelly Belly p/b Kenda.

Stage 4 was a tough one.

With about six miles until the first Nissan King of the Mountains (KOM) competition of the day, Jason McCartney (USA) of Bissell Pro Cycling made a move to bridge the gap up to the break, but wouldn't be able to make the catch until later in the race.

Heading up the Category 4 climb at CR 27, Cooke led the way, reaching the top first and adding to his lead in the KOM Jersey competition, followed by Villella and Duggan. Charging at high speeds down into the small town of Oak Creek, the break approached the first and only Clif Bar sprint of the day. Siutsou barreled through the line first, followed by Warbasse and Duggan.

Heading uphill and through the Feed Zone, the riders started the ascent of the second Nissan KOM competition, a Category 4 climb at CO 131. Cooke reached the top first in an uncontested effort to increase his hold on the KOM Jersey, followed by Pate and Tvetcov.

During the descent, the break started losing time to the chasing peloton, reaching just under three minutes as they hit the valley floor. But as the peloton got closer to the top of the KOM, the gap increased again. Sensing the fate of the break, Siutsou seized the moment and attacked. He was joined by Gallopin, Warbasse, Rogers and Villella.

As they continued approaching the third Nissan KOM competition of the day, again a Category 4 at CO 131, Pate and McCartney were reabsorbed by the Garmin-led peloton. This time Gallopin crested the climb first, followed by Siutsou and Rogers. On the 15-mile stretch through the valley leading into the biggest climb of the stage at Bachelor Gulch, Duggan lost contact with the chase, leaving just Tvetcov and Cooke in pursuit of the five ahead, but before long they were caught as well.

With just about 25 miles left to the uphill finish line in Beaver Creek, the peloton started pushing the pace, with various teams jumping to the front in an effort to eventually reel back in the break. On a false flat leading into the fourth Nissan KOM competition of the day, Team Garmin-Sharp and BMC Racing Team controlled the front of the peloton, with lots of shuffling going on in the bunch as everyone got into position.

The tough climb up Bachelor Gulch shattered the field. On the ascent, Rogers attacked the break, followed by Warbasse, leaving Gallopin and Villella chasing behind, and Siutsou falling back to the main group. But in the final three miles of the climb, Warbasse lost contact as well. The climb continued to break apart the riders leaving Rogers out front, followed by three chasers, then eight additional riders, followed by the peloton, and then the grupetto trying to hang on.

As things continued to shake up, Mathias Frank (SUI) of BMC Racing Team, van Garderen, Tom Danielson (USA) of Team Garmin-Sharp and Acevedo, formed the group chasing down Rogers, which eventually they did and then proceeded to drop him on the climb.

Powering over the top, Danielson led, with van Garderen and Acevedo following. Now, with just more than seven miles to go until the finish in Beaver Creek, the pressure was building. On the descent, Acevedo attacked and was challenged by van Garderen, leaving Danielson, and eventually Frank, chasing just a few seconds back. Behind them a group of eight, including race leader Lachlan Morton (AUS) of Team Garmin-Sharp was keeping pace at only about 30 seconds back.

The stage 4 profile tells the story of the day: pain.

"The biggest challenge was the bottom of Bachelor Gulch. It was an insanely hard tempo," said van Garderen.

As the rain began to pound down on the riders, van Garderen and Acevedo powered through the final climb, lined with eagerly awaiting fans, to the finish line in Beaver Creek. Acevedo eventually took the stage, followed by van Garderen and 13 seconds later, Frank.

"I felt very good and confident," said Acevedo. "I had to go as easy as I could going downhill, taking as little risk possible going around corners. I had a tremendous day today and I felt good about it. For me to win today is just amazing."

The biggest change in today's jerseys was van Garderen taking the Smashburger Leader Jersey. Rogers was awarded the FirstBank Most Courageous Rider Jersey for his work in the breaks. Several jerseys remain unchanged, including the Clif Bar Sprint Jersey (Peter Sagan (SVK) of Cannondale Pro Cycling), Nissan King of the Mountains Jersey (Cooke) and Colorado State University Best Young Rider Jersey (Morton).

Friday, Aug. 23 - Vail Individual Time Trial (16.1 km/10 mi)
Start Time: 1:05 p.m. MT
Estimated Finish Time: 3:50 p.m. MT
Satellite Feed Time: 4:30-4:45 p.m. MT

The Vail time trial has a distinctly uphill profile.

The last time the USA Pro Challenge visited Vail, the Time Trial was decided by 58 hundredths of a second. Competition will be equally fierce this time around, but the names may change a bit. The course's roots are in Colorado racing lore and trace back to the Coors Classic. Starting in Vail and climbing most of the way up Vail Pass, the route is no easy proposition, even for the best racers on earth. The gentle grades of the first half of the course give way to a steady climb for the last three miles. But it takes more than legs on this strategic course; go too hard early and the climb may kill your chances, but conserve too much for the climb and the leaderboard may be out of reach.
