Welsh cyclist Luke Rowe has broken his leg while white-water rafting during his brother’s stag party in Prague.

Just weeks after helping Chris Froome to his fourth Tour de France title having broken a rib in the opening stage, Rowe is facing a long injury lay-off.

The 27-year-old Team Sky rider, Froome’s road captain during the tour, is recovering at home in Cardiff after surgery.

“My brother Matt is getting married and so I was away with family and friends for his ‘stag party’,” he said.

“On the first morning we went whitewater rafting. I jumped down into the water but landed in a shallow section on my right leg.

“Being a bike rider you get in a lot of scrapes and you get used to injuries, but I knew straight away that it was a bad one.

“It’s early days but I’m determined to get back racing as soon as I can.”

Brother Matt is getting married to long-term girlfriend Dani King, the Olympic 2012 team pursuit champion.

Rowe’s coach, Rod Ellingworth, said: “Obviously it’s a serious injury and so Luke’s going to be off the bike for a while.

“An injury like this is a test of character for anyone, but character is something Luke has plenty of.

“He’s a really important part of our team and, as a team, we’ll be right behind him throughout his recovery.”
