Bach's IOC legacy rides on response

Thomas Bach's response to a report that concluded Russia concealed hundreds of positive doping tests ahead of the 2014 Sochi Winter Games will determine his legacy as International Olympic Committee president, athletes said on Monday.

The IOC promised the "toughest sanctions available" following the release of the report, which revealed evidence of widespread state-sponsored doping by Russian athletes.

IOC athletes commission member Adam Pengilly, a British skeleton racer, urged Bach to follow the recommendation of the WADA report and ban all Russian competitors from the upcoming Rio Olympics.
