Michael Phelps smiles as he climbs Hayes Hill for the 98th running of Bay to Breakers in 90+ degree heat in San Francisco on Sunday May 17, 2009.
The chief sponsor of San Francisco's Bay to Breakers race has pulled its support.
A spokesman for insurance giant ING said in a statement that the company had reached its goal with the race. Spokesman Joseph Loparco added that ING wishes the event "many more years of success."
The run has become famous for contestants in wacky costumes, or no costume at all, and racers who become drunk and urinate on residents' lawns.
Next year's event will celebrate the 100th anniversary of the race.
