Number 100 is supposed to be a historic run for the Bay to Breakers, but it could be a last hurrah.
There is no title sponsor for the race, nor has it been profitable in years past. Race owner Philip Anschutz will not disclose how much the race loses every year, but he says it definitely lose money.
In addition, residents and city officials are not happy with the public urination, vomiting, trash and boozing that seem to line the race route.
Participation for this year's race was capped at 50,000 and alcohol and floats are banned. One San Francisco supervisor says this will be a test to see if the race has truly changed its stripes.
So far there has been unprecedented registration for the Bay to Breakers. Already four of the five starting corrals are sold out.
