A man collapsed while running in the 101st Zazzle Bay to Breakers race Sunday.
About 8 a.m., the man went down at Hayes and Laguna streets, according to racers running beside him. One participant said he did not notice the man before he collapsed and could not say whether the man was struggling during the run.
That same participant stopped racing to help the man, holding up his neck while another runner summoned police. The Fire Department also responded to the scene.
Medics performed CPR on the collapsed man for roughly 15 minutes before he was taken to a nearby hospital.
In all, four medical-related calls were made throughout the race. And at least one other person was taken to a hospital.
The conditions of all those treated were not immediately known.
