Three major climbs to test Giro riders

Restarting today after Monday's rest day, the riders in the Giro d'Italia will face what could be the most decisive stage of this year's event. Although stage 16 is just 139 kilometres in length, it scales three major climbs, namely the Passo Gavia, the Passo Dello Stelvio and then the uphill battle to the line at the Val Martello Martelltal.

All three are over two thousand metres, with the Stelvio reaching 2,758 metres above sea level and representing the highest point of this year’s race.

The effects of altitude will likely have a major effect on the final outcome, potentially favouring the Colombian riders who are more accustomed to such heights.

If so, race leader Rigoberto Uran (Omega Pharma Quick Step) and fifth-placed Nairo Quintanta (Movistar) will seek to maximise their chances to gain time on the other riders.

However, it is possibe the stage will be amended or cancelled as organisers are concerned about the possibility of snow and will make a final decision this morning.
