Bashir Abdi, a 37-year-old Belgian runner, withdrew from the Chicago Marathon due to a calf tear. Abdi, who holds the European record, suffered the injury during final training in Flagstaff. He had been preparing for the marathon for months, but recovery takes priority.

Abdi had spent time training at altitude in France and Arizona. The injury occurred in his final track session. Despite the setback, Abdi remains focused on his next goal. A second marathon this year is still possible, depending on recovery. Read more racing coverage.

Abdi's withdrawal leaves the Chicago Marathon with six runners who have broken 2:04. The race will still feature strong competition, including defending champion Jacob Kiplimo. Abdi's potential return could be in New York or Valencia. Related: Waukesha Runner Dies at Milwaukee Lakefront Half Marathon.
