BEAVER CREEK - A late climb on Bachelor Gulch shook up an elite field of cyclists and shook up the overall standings Thursday afternoon at the USA Pro Challenge.
Aspen resident Tejay van Garderen seized the yellow jersey as overall leader with a strong effort up the steep hill and sits in great position with three stages left. The BMC rider finished second overall in last year's race.
Colombian Calle Acevedo won Stage 4 in a downpour with van Garderen right behind him. Swiss rider Mathias Frank finished third.
While a large group of riders started the 3-plus-mile ascent of Bachelor Gulch together with hopes of chasing down a breakaway, it didn't take long for that group to fall apart. One of the first to be dropped was defending champion Christian Vande Velde of Garmin-Sharp. A few seconds later, the man wearing the yellow jersey, Lachlan Morton, also of Garmin, cracked.
A group of three - van Garderen, Acevedo and Tom Danielson - topped the climb first. But Danielson couldn't keep up on the quick descent.
The seven-day stage race continues Friday with a 10-mile time trial and it concludes Sunday in Denver.
