Colombian Rigoberto Urán burst back into contention at the Tour de Suisse on Saturday with a sizzling
time-trial win ahead of a last-day showdown in the Alps.

Ineos Ecuadorian Richard Carapaz was fourth fastest to retain the overall
lead after the peculiar, high-altitude 23km time-trial with a 6.5 percent
gradient ascent that peaked at 2,046m followed by a similar descent.

Urán was quickest to the summit of the Oberalp pass and then went all out
in a high-stakes descent to set up a tense finale Sunday on a stage that
includes three peaks and 40km of climbing.

The 34-year-old Urán trails Carapaz by just 17 seconds.

French world champion Julian Alaphilippe was second on the day to stay in
contention, but is expected to leave the race as his partner is about to give
birth.
