Marathon organizers have demanded an urgent meeting with officials after the reinstatement of Russian drug cheat Lilya Shobukhova despite the fact she has not repaid around $3 million in prize money earned when she was doping.

Sources within the World Marathon Majors, the series of the five richest big-city events, said the IAAF may be acting in breach of its own rules by reinstating an athlete before he or she has returned money won from their events.

Shobukhova's best marathon time of 2 hours, 18 minutes, 20 seconds made her the second-fastest woman ever but checks on her biological passport found abnormalities.
