LONDON — Stricter anti-doping penalties will be applied to elite athletes in the World Marathon Majors (WMM), the series that brings together six of the world's top races, organizers said Friday. Tokyo, Boston, London, Berlin, Chicago and New York have revised their athlete contracts to include new provisions that include the right to suspend payment and demand repayments of prize money, appearance fees and performance bonuses. The sanctions will be triggered for any athlete “found in violation of a criminal offense involving drugs, anti-doping rules, or if for any other reason the athlete's result has been nullified,” WMM said in a statement. — Reuters
