“Whilst you want to race and put on the best show, you could see how many crashes there were and that was with the three descents at a very careful speed,” said Rowe, who was thrown off last year’s Tour for a punch.

In the absence of previous winners Chris Froome and Geraint Thomas, 30-year-old Rowe from Cardiff might not be the key rider at Ineos.

However, he is an influential voice even if rivals may not want to hear him.

Rowe claimed Colombian rider Miguel Angel Lopez and his Astana team had not cooperated with the truce.

Lopez crashed heavily into a traffic sign.

“As a result their leader was left on his back. They made themselves look pretty stupid,” Rowe said.

The Tour de France should have been held in June, but the two-month delay due to the coronavirus pandemic means more poor weather is expected.

“Most teams had like four of their riders hit the ground,” Rowe said.

“The problem was it hasn’t rained for two, three months, then it rains and it was literally like ice.

“I think half the teams had around half of their team who hit the ground today.”

Accidents in cycling have been headline events in recent weeks.

Belgian rookie Remco Evenepoel plunged head first into a ravine at the Tour of Lombardy while sprinter Fabio Jakobsen said he felt “lucky to be alive” after a horror crash at the Tour of Poland.

“We got this riders organisation with a couple of guys in each team and we spoke about it last night, how we can look after each other when needed,” Rowe said.

His team leader and defending Tour champion Egan Bernal looked calm and relaxed after the stage.

“It was a really dangerous race but I’m OK, it was quite stressful. There were a tremendous amount of falls and you really had to concentrate,” said the 23-year-old.

Bora-Hansgrohe rider Peter Sagan, fifth on Saturday, said “the last mile was crazy”.

“Actually the last five was entirely with a headwind. Everyone was nervous. It was a huge mess. All sprints like that, with a headwind, are always a lottery,” said the former world champion.

Ireland’s Sam Bennett of the Deceuninck team, who was fourth, said the truce was the correct decision.

“It was a dangerous day with the road so slippery,” he said.

“I was fine on the climb, the problem was that we went slow and neutralised the descent. Others were able to get into the peloton.

“But I think it was a good decision to do everything to be safe even if when you have made an effort, you want the race to continue.”
