Norwegian Alexander Kristoff took his 20th victory of the 2015 season on Sunday, winning the GP Plouay in France, and propelling his Katusha team to the top of the UCI WorldTour rankings, unseating British squad Sky.

Kristoff took the win ahead of Simone Ponzi (Southeast) in second and Ramunas Navardauskas (Cannondale-Garmin) in third. His 80 points for winning Plouay mean that Kristoff moves from fifth to fourth in the individual WorldTour ranking. Kristoff’s most notable 2015 WorldTour victory was the Tour of Flanders in April, and he has also won stages of Paris-Nice and the Tour de Suisse.

Spaniard Alejandro Valverde (Movistar) still leads the ranking ahead of Tour de France winner and top-placed British rider Chris Froome (Sky), with Giro d’Italia winner Alberto Contador (Tinkoff-Saxo) in third. Welshman Geraint Thomas (Sky) is ninth.

Katusha now collectively have 1270 points to Sky’s 1246, with Movistar in third with 1242 – and incredibly close trio at the top.

Alexander Kristoff wins the 2015 GP Plouay – and Katusha are now at the top of the WorldTour team ranking

The next events in the 2015 WorldTour calendar are the Grand Prix Cycliste de Québec Grand Prix Cycliste de Montréal on September 11 and 13. The currently running Vuelta a España concludes on September 13.

WorldTour points are awarded for one-day race, tour stage and stage race overall finishing positions for counting events. The amount of points awarded depends on the ranking of the event. For example, winning the Tour de France overall gives a rider twice as many points as winning the Eneco Tour overall.

Valverde topped the 2014 WorldTour ranking; top British rider was Froome in seventh.
