Phil Gore, after running 1,019.3 km in six days, faces surgery for leg infection. Gore completed a 6.7-km loop hourly for 152 hours in Project 168. Initially diagnosed with a hematoma, Gore returned to hospital for a second opinion.

Doctors found pus, indicating an abscess, not a hematoma. Gore is scheduled for surgery to clean the area. This setback likely prevents his participation in the Satellite Championships. Gore aimed to test his limits, not break records, in Project 168. Read more trail coverage.

Despite raising over A$300,000 for charity, Gore's recovery is complicated. He remains grounded, acknowledging the severity of his condition. Gore hopes to return to running after recovery. Related: Cornwall ultrarunner sets new Vermont Long Trail speed record.
