Jonathan Edwards presents coverage of the men's and women's time trials as the 2013 Road World Championships in Florence get under way.

All eyes will be on Britain's Bradley Wiggins, who is looking to upgrade the silver he won in 2011 to gold. After an amazing 2012, when he won the Tour de France and Olympic gold, injury and illness have meant this year has been a disappointing one for Wiggins. But the 33-year-old has targeted this event and has been building up his weight to give him extra power on the flat and fast course that stretches for more than 35 miles of scenic Tuscan countryside before ending in the historic city of Florence.
