The 32km solo test could be the decisive moment for Simon Yates and Nairo Quintana

The third week of the Vuelta a España kicks off with Simon Yates back in the leader’s jersey.

After a rest day on Monday, Yates now must defend his lead on a 32km individual time trial through northern Spain.

The course starts from the town of Santillana del Mar and loops around before heading back west to the finish in Torrelavega.

A rolling profile offers the perfect opportunity for the TT specialists to thrive, but will be a major hurdle for the general classification contenders.

Mitchelton-Scott star Simon Yates leads the Vuelta by 26 seconds over the second place Spaniard Alejandro Valverde (Movistar).

Colombian climber Nairo Quintana, Valverde’s Movistar team-mate, is just behind in third place at 26 seconds.

But the stage 16 individual time trial could up-end the overall classification, as the climbers try to hold on to their advantage against more powerful contenders over the flat course.

All times listed here are Central European Summer Time, so subtract an hour for British Summer Time.

The first rider heads off the start ramp just after 2pm, with the top 10 setting at around 4.45pm.

Yates is scheduled ride just after 5pm.
