Prati di Tivo could prove decisive at Tirreno-Adriatico

The overall contenders at Tirreno-Adriatico face a potentially decisive day on Saturday as they tackle stage 4 from Narni to the summit finish at Prati di Tivo. The 173km stage brings the peloton from Umbria high into the Apennines near the Gran Sasso d’Italia and promises to dramatically alter the look of the general classification after successive bunch finishes.
