Should athletes who test positive for banned substances receive a lifetime ban from major marathons?
Professional marathon runners face a wave of suspensions from the Athletics Integrity Unit just days before the 2026 New York City Marathon on Nov. 1. This integrity crackdown recently prompted the disqualification of a competitor, resulting in runner Patrick Dever moving to third place for the 2025 race.
Why it matters
The Athletics Integrity Unit mandates that disqualified athletes forfeit prize money and face multi-year bans, directly impacting race standings and earnings for clean competitors. These enforcement actions serve to uphold competitive standards and financial integrity across major marathons.
Official disciplinary records from the Athletics Integrity Unit document multi-year bans for doping violations, including a three-year suspension for Ruth Chepngetich and a six-year term for Ruti Aga. The full extent of individual career impacts following these positive tests remains under review.
The players
Athletics Integrity Unit
The independent body responsible for managing anti-doping and integrity programs in international distance running.
Patrick Dever
A professional marathon runner who recently moved to third place in the 2025 New York City Marathon standings.
Peres Jepchirchir
A professional runner who received a provisional five-year suspension for a positive EPO test.
Ruti Aga
A professional athlete issued a six-year suspension following a positive test for methylprednisolone.
Ruth Chepngetich
A runner who received a three-year suspension after testing positive for HCTZ.
The details
The Athletics Integrity Unit monitors professional runners for banned substances through rigorous testing protocols. When an athlete tests positive, race organizers withhold prize money, such as the $100,000 awarded for first place, until a formal clearing process occurs. Patrick Dever received an additional $15,000 after his promotion to third place in 2025, reflecting the difference between third and fourth place payouts.
Timeline

Oct. 22, 2026: Ruti Aga received a six-year suspension for testing positive for methylprednisolone.
Oct. 23, 2026: Peres Jepchirchir received a provisional five-year suspension for testing positive for EPO.

Health Landscape
The current wave of suspensions marks a departure from the absolute lifetime bans enforced by the World Marathon Majors. These enforcement actions highlight an evolving regulatory environment focused on retroactive prize redistribution and strict adherence to prohibited substance lists.
While these enforcement actions primarily concern professional athlete eligibility, they underscore the importance of transparency in performance-enhancing substance regulations. Readers interested in the impact of these substances on physiology or performance should consult with a qualified sports medicine physician.
The takeaway
Maintaining the integrity of professional sport remains a primary focus of international anti-doping bodies as they continue to investigate performance-related violations. For those interested in fitness recovery and performance, focus on evidence-based training and nutrition protocols validated by sports health professionals.
