Drug testing ran smoothly at this year's Tour de France but the International Cycling Union should consider introducing night checks, the World Anti-Doping Agency said.

WADA sent observers to the Tour in July to assess anti-doping procedures as Alberto Contador recorded his third win in the race.
The Spaniard later failed a test for the banned agent clenbuterol. He denied doping and blamed the result on contaminated meat.
""It is rare to see an international federation conduct such a comprehensive anti-doping programme,"" WADA said in a report.
""The team at the UCI should be congratulated on both their execution of the programme and their willingness to adapt, modify and try new approaches throughout this Tour.""
However, the Independent Observer Team made a few recommendations to the UCI governing body including a suggestion that riders be tested at night.
