UnitedHealthcare's Kiel Reijnen has won the third stage of the US Pro Tour Challenge.
In a race dominated by BMC, stage three was a 163km stage from Copper Mountain to Aspen.
After ten kilometres of a stage which had Brent Bookwalter as its leader, Daniel Jaramillo of Jamis - Hagens Berman was first over the category four Fremont Pass.
That sparked a break which included Jesus Hernandez (Tinkoff-Saxo), Laurent Didier (Trek), Janier Acevedo (Cannondale-Garmin), Miguel Benito and Kyle Murphy (Caja Rural-Seguros RGA), Timothy Roe (Drapac), Dion Smith and Joseph Lewis (Hincapie), Daniel Jaramillo (Jamis - Hagens Berman), Daniel Eaton (Axeon) and Jack Bobridge (Team Budget Forklifts).
This group got three minutes away after fifty kilometres before they headed into Leadville where there were big crowds to see Jesus Hernandez Blazquez of Tinkoff-Saxo take the sprint points.ahead of Murphy and Jaramilo.
Alongside the Arkansas River and speeds were reaching 60kph, Jaramilo took the second sprint at Twin Peaks after 103.3kms with the front group some 3.30 ahead of the peloton.
BMC put the pressure on and the gap came down to 2.41 as the front group prepared to take on the main climb of the day up Independence Pass which is 12.095 feet above sea level.
The upcoming climb forced a split in the break and Bobridge, Smith and Didier quickly built a lead of 25 seconds on the chasers before Laurent Didier of Trek Factory left them and went away with just under forty kilometres to go, taking a ten second gap whilst the peloton started to get up to some of the chasers.
Didier from Luzembourg sailed over Independence Pass to take the points before starting on the descent with 31.9kms left.
His time on the front did not last and and with 24kms left, a group of ten were now in control until Rohan Dennis brought up the peloton two kilometres later and everyone was back together.
With 6.4kms left, BMC were on the front before Jack Bobridge and Rohan Dennis sneaked off away.
Two riders who had both under-taken the world hour record was always going to be a worry to the peoton, so they were shut down by Lachlan Morton.
Gavin Mannion tried a sneaky move down the left but he was brought back with two kilometres to go.
Under the flam rogue and Michal Schar or BMC was leading the peloton but the sprint was on and Colorado based Kiel Reijnen of UnitedHealthcare rode away to win in 3.56.02 ahead of Rohan Dennis and Ruben Zepunkte.
