Bank of America Chicago Marathon anti-doping policy

The Bank of America Chicago Marathon, as a World Athletics Platinum Label event, strictly adheres to the rules, regulations and anti-doping processes set forth by World Athletics. The Chicago Marathon supports all Anti-Doping Rules and Anti-Doping Regulations and drug testing procedures and protocols both in and out of competition.

Every professional athlete who competes in the Chicago Marathon’s elite field is subject to drug testing. If an athlete receives a ban from World Athletics based on a drug test (in or out of competition) or findings from the Athlete’s Biological Passport (ABP), the athlete’s records will be annulled and the standing of athletes who placed behind the disqualified athlete will be updated.

In addition, any athlete who receives or has received a doping ban in the past, including those who have been reinstated after a period of ineligibility, will not be invited to participate in the Bank of America Chicago Marathon.

The Bank of America Chicago Marathon has been and continues to be an advocate for strict anti-doping measures in the sport, along with the other events that comprise the Abbott World Marathon Majors.
