I ran a HM on Saturday in San Diego. Large event, early morning start at 6 a.m. About 8 miles into the race, we get onto a divided highway where the runners are using two lanes, and the traffic is in one direction, the same as that of the runners, on the other side of the divider. Traffic is very slow, about as slow as we are running.
From his car, a white male starts screaming obscenities and threatening us, the runners. He gets booed, but continues. This goes on for about 3-4 minutes, and lo and behold, we hear a siren and see 2 policemen on motor cycles appear behind him. Cheers all over!
