World Athletics announced on Friday that it had cancelled the 2025 Road Running Championships, a month after it was moved from the initial host city of San Diego.
Track and field's governing body said it had "held discussions with a number of alternative hosts, some with great potential" for the championships that had been scheduled for September 26-28.
"While some of these discussions will continue for other editions of the event, the World Athletics Council has decided not to award the Championships to an alternative host this year due to lack of essential planning and preparation time required to cater for both elite and mass participation race elements," it said.
The next World Road Running Championships will now be held in Copenhagen on September 19-20, 2026.
