CYCLING NEWS - Four-time Tour de France winner Chris Froome failed a urine test at the Vuelta a Espana in September but the Briton said on Wednesday he had done nothing wrong.
Froome, 32, who won the Spanish race, explained in a statement that he had followed medical advice and taken an increased dosage of asthma medication without exceeding the permitted limits.
Cycling's world governing body, the UCI, said in a statement it had notified Froome on September 20 of an 'Adverse Analytical Finding" from a sample collected after Stage 18 of the race on September 7.
The sample had double the permissible limit of Salbutamol, which is permitted as a legal asthma drug by the World Anti-Doping Agency.
"It is well known that I have asthma and I know exactly what the rules are," the rider said in a statement issued by Team Sky.
"I use an inhaler to manage my symptoms (always within the permissible limits) and I know for sure that I will be tested every day I wear the race leader's jersey."
Froome said his asthma had worsened at the Vuelta so he followed the team doctor's advice and increased his Salbutamol dosage.
"As always, I took the greatest care to ensure that I did not use more than the permissible dose," he said.
