ASPEN, Colo. (AP) Kiel Reijnen of UnitedHealthCare Pro Cycling won the first stage of the USA Pro Challenge on Monday, edging Alex Howes of Garmin-Sharp in a two-man sprint across the finish line.

Reijnen and Howes completed the 61-mile route in 2 hours, 26 minutes, 35 seconds.

Four riders were three seconds back: Ben Hermans (BMC Racing), Carter Jones (Optum), Matthew Busche (Trek Factory) and Javier Megias Leal (Team Novo Nordisk).

Defending champion Tejay van Garderen, the favorite in the 16-team race, finished in a pack of 15 riders that crossed the finish line 12 seconds behind Reijnen and Howes.

The 128-rider field will race 110 miles from Aspen to Crested Butte on Tuesday.
