Seb Coe: Doping in sport 'don't test...don't catch'

Former Olympic gold medallist Seb Coe says he believes athletics is winning the battle against doping in the sport. Following recent doping scandals, he tells 5 live athletics correspondent Mike Costello that in athletics, they test 10-times more than any other sport.

Coe, who is now attempting to become the most powerful man in track and field by becoming the IAAF president, insists 'If you don't test, you don't catch'.
