Geraint Thomas

The 37 year-old went into today's crucial time trial on Monte Lussari with a 26-second lead but saw that slip away.

The Welshman was looking good for a medal in the road race five years ago before landing in a gutter on the final descent around 10km from the finish line.

The Welshman was the first to come down as another day of crashes again brought chaos to the race. He is due to be reassessed before starting stage four.
