The 2017 Criterium du Dauphine stage 4 23.5 km time trial from La Tour-du-Pin to Bourgoin-Jallieu will see the first major shake up the general classification. Aleksejs Saramotins (Bora-Hansgrohe) will be the first of the 169 starters on Wednesday afternoon, rolling out of the start house at 1:01 pm local time.
Race leader Thomas De Gendt of Lotto Soudal is the last man off at 3:50 pm with one-minute intervals between all riders.
The group of GC favourites headlined by Chris Froome (Team Sky), Richie Porte (BMC), Alejandro Valverde (Movistar), Alberto Contador (Trek-Segafredo) and Romain Bardet (AG2R-La Mondiale) start the stage all timed on time. The test against the clock will see a selection with the possibility of a yellow jersey for the likes of Froome and Porte are expected to also challenge for the stage honours.
