Scotland's David Millar has withdrawn from the Giro d'Italia.

Millar described his debut in the race last year as a 'nightmare' and his feelings won't have changed this time around.

He was targeting a team time trial win in Venice but settled for second while he also disappointed in the this week's individual time trial, finishing 31st.

Millar failed to complete a difficult day in the Apennines, which took the pelton across a series of category climbs in searing heat.
