REIGNING Tour de France champion Geraint Thomas and four-time Tour winner Chris Froome have been named on Great Britain's long list for the UCI Road World Championships in Innsbruck next month.

Team Sky duo Froome and Thomas, who between them hold all three Grand Tour titles at present, are on the long list for both the men's road race and the time trial.

The road race squad also includes twins Simon and Adam Yates, and British national champion Connor Swift.

Sisters Alice and Hannah Barnes are on the list of the women's road race and time trial, while Dani Rowe - who won bronze at the Commonwealth Games in April - is listed for the road race.

The routes for both road races promise to be tough, with the men's route including over 5,000 metres of climbing in a 265km course around Innsbruck. The women's race uses much of the same route but is 162.5km long.

"This year's road world championship course is one for the climbers, and I'm pleased to see we have so many talented British riders selected for the long list whose strengths match the nature of the course," British Cycling performance director Stephen Park said.

"I'm particularly thrilled that Geraint Thomas, Chris Froome and Simon Yates have made themselves available for selection this year, having made our country so proud in the three biggest races of the calendar."

The under-23 men's squad includes team pursuit world champions Ethan Hayter and Charlie Tanfield, while junior cyclo-cross world champion Ben Tulett is in the junior men's squad. Pfeiffer Georgi headlines the longlist for the junior women's races.

The world championships will be held in Innsbruck from September 23-30, with organisers then handing over to Yorkshire which will host the 2019 edition.
