The run is also known as the "Happiest Race on Earth."
The 13.1-mile race began near Downtown Disney before sunrise, and it went through Disney's California Adventure and /*Disneyland*/ before looping through the streets of /*Anaheim*/.
Paul Negay is this year's winner, crossing at an unofficial time of 1 hour, 7 minutes and 25 seconds.
Rachel Booth of Mountain View was the first woman to cross the finish line at 1 hour, 15 minutes and 20 seconds.
"I was actually faster than the fastest pace I wanted to go all morning, so it was a really good day. I was out there having fun and it kind of all just fell in place" said Booth.
Disney is the parent company of ABC7.
