The 2025 IAU 50km World Championships, scheduled for December 7 in New Delhi, won’t go ahead as planned. The race was postponed this week after Delhi authorities ordered all sports events set for November and December to be shifted to later months, citing escalating air-quality issues across the capital.
The directive, issued November 20 by the Government of the National Capital Territory of Delhi, left organizers with little room to maneuver. After discussions with the Athletics Federation of India and the Local Organizing Committee, the IAU confirmed the decision on November 22 and said a new date would be announced within a week.
Although postponements are never welcome this close to an event, the environmental issues have been impossible to ignore.
In the days leading up to the announcement, New Delhi’s Air Quality Index hovered around 370 ppm, a level considered “severe.” Schools have already been asked to suspend outdoor activity for as long as two months, following guidance from India’s Supreme Court and the Commission for Air Quality Management.
Late-autumn air pollution spikes are a familiar pattern in the region. Winter inversions trap emissions over the city, while crop-burning in neighboring states adds another surge of particulate matter. Since 2015, fine-particulate readings in November and December have routinely approached or exceeded 300 ppm.
The IAU acknowledged the disruption for teams that had finalized travel and tapered training. In its statement, the federation emphasized that the health and safety of athletes and staff “must remain our highest priority,” and noted that the government’s directive required full compliance.
India last hosted the event in 2023 in Hyderabad, where conditions were far more stable. That race produced strong fields and memorable podiums, which partly explains why so many athletes were eager to return.
Teams and athletes will now wait for the updated date and adapt their plans around it, while organizers continue to monitor conditions in one of the world’s most heavily polluted megacities.
