The Boston Athletic Association is to pay prize money to athletes who finished behind doping offenders at their races. The organizer of the world's oldest annual marathon said on Tuesday it was in the process of contacting athletes entitled to prizes after their results were re-ranked due to disqualification.

The Boston Marathon is finally paying runners who were due prize money after other runners who finished ahead of them were later disqualified for doping.

The Boston Athletic Association said it will issue voluntary payments to athletes who were adversely affected by doping offenses at B.A.A. events.

The Boston Athletic Association is looking to identify athletes who were knocked down in the rankings by others who were later disqualified for doping. The organization is seeking out athletes who moved up the ranks after doping disqualifications so they can be paid out prize money they would have won.
