TEHRAN, Iran — Iran’s capital held its first international marathon Friday, which was billed as an opportunity for “building bridges” though American runners were largely absent.

The head of Iran’s Track and Field Federation, Majid Keyhani, had said there was no ban on any nationality in what he called the “Persian Run.”

The course took male runners from the Azadi Sports Complex through the Azadi square in western Tehran. Women ran separately, inside the Azadi sports complex.

The race’s website listed 28 Americans among the registered runners, along with participants from more than 40 countries, including Britain, Canada and Saudi Arabia. Keyhani said all the names were submitted to the Foreign Ministry for issuing visas.

Iran stopped issuing visas to U.S. citizens after President Trump first announced a travel ban on Iranians and citizens of six other Muslim-majority countries in January.
