More than 21,000 people filled the streets downtown for the annual ThunderCloud Subs Turkey Trot. The five mile route began on the South 1st Street Bridge and finished in front of the Long Center on Riverside Drive.
Many people dressed up and brought their dogs.
"I dressed as a banana because it makes people smile," said Melody Taylor.
This is Taylor's sixth year participating in the largest five mile run in Texas.
The Austin tradition reminds us not everyone eats a feast on Thanksgiving.
"By having this marathon it helps support a lot of people," said Donald Young, Turkey Trot participant.
Caritas of Austin receives 100-percent of the money raised, to work toward ending poverty and homelessness in Central Texas.
"That's why I love Austin because everybody seems to come together, have a great time and it's one big happy family," said Riley Sahm, another participant.
Since 1991, this event has raised more than $1.5 million for Caritas of Austin.
