GRENCHEN, SWITZERLAND -- Time trial specialist Filippo Ganna broke cycling's hour record when he covered 56.792 kilometres in 60 minutes on Saturday.

The Italian extended the record by more than 1.2 kilometres, the biggest jump in seven years.

Asked to describe the pain of the last five minutes, he said, "I lost energy to try to go for 57, but nothing (in the legs)."

He said he was open to another attempt at a different time of the season, when he was fresher.

Ganna took the record from British teammate Dan Bigham, who made his mark at the same Swiss velodrome on Aug. 19.
