British Cycling Head Coach Shane Sutton backs Welsh rider Geraint Thomas to be a future Grand Tour winner.Read the full story ›
Geraint Thomas has taken the overall lead at the first major European stage race of the UCI World Tour season, Paris-Nice.
The Cardiff-born rider finished the day's fourth stage in second place behind Dutch Garmin Sharp rider Tom-Jelte Slagter to take the overall lead ahead of Germany's John Degenkolb by three seconds.
Thomas's Team Sky rode from the front of the peloton throughout the closing 40km before the reigning Olympic track champion broke free of the lead group alongside Slagter, the pair holding on to fight out a sprint finish.
The ride means Thomas holds the slim overall lead at the halfway stage of the race and adds further to his reputation as a Grand Tour General Classification contender of the future.

Welsh Adventurer reveals the excruciating pain and agony she went through to cycle to the South PoleRead the full story ›
Cameras follow Welsh adventurer Maria Leijerstam as she bids to set a world record by cycling to the South Pole.
Wales This Week - The White Ice Cycle, Tuesday after News At Ten, on ITV Cymru Wales
An adventurer from the Vale of Glamorgan has achieved a world first by cycling to the South Pole from the edge of the continent in just 10 days. Maria Leijerstam managed the feat this Friday morning following a gruelling 500 mile ride in "vicious" conditions.
The 35-year-old set off from the Novo Russian air force base on December 16 and went head to head against two other male riders. Her team said at one point the sweat on the inside of her boots froze and she heated her freeze-dried food by melting snow on a small stove inside her wind blasted tent.
However, the former management consultant dug deep and pedalled her way into the record books while on a customised recumbent bike PolarCycle. Ms Leijerstam's mother Adrianne said her daughter's success was due to "meticulous planning, super fitness and pure determination".
Before setting out on her journey the extreme cyclist said: "I've had to get my body prepared for burning fat and not carbohydrates, so I've been training for two to three hours on an empty stomach which teaches my body to become more efficient."
It's Christmas Day but for Maria it means another hard day of cycling.
She's cycled 81km per day. On a continent where it never gets dark she has spent as little time as possible sleeping and maximum time she can cycling.
Maria is determined to reach the South Pole within the next three days.
In her blog yesterday she described the Antartica as vicious but beautiful.

Welsh adventurer Maria Leijerstam is well ahead of her two male rivals in the race to claim a world first cycle title this Christmas.
Although Maria, 35, from the Vale of Glamorgan started days later and took a different route to the South Pole from the edge of the continent, her average of 40 km per day is putting her well in the running for a first.
With over 45kg of food and fuel, Maria started her journey started on 17th December.
After the first 80km she spent two days cycling up the Leverett glacier against very strong wind.
Fresh snow is making the task difficult and increasing the drag but she is continuing to travel 40-60 km per day.
She will spend both Christmas day and New Years day cycling in temperatures as low as minus 40 degrees with the aim of reaching the South Pole by 7th January 2014.
