Deborah Cannon/American-Statesman The elite group of runners take off on the First Street bridge during the Schlotzsky’s 5K Bun Run on Sunday, April 25, 2004.

So, honestly, how would you rate your buns?

Registration is open for the 33rd annual Schlotzsky’s Bun Run, where the top male and female winners collect cash prizes and teams can earn honors for Austin’s Fittest Buns, Austin’s Fastest Buns, Austin’s Best Lookin’ Buns and Austin’s Most Generous Buns.

This year’s race is scheduled for Sept. 27, and besides the timed 5K run, the event includes a Kids K race for children 12 and under. Dogs can even run alongside their owners to compete for the title of Fastest Dog in Austin.

The kids race starts at 8 a.m. and the 5K starts at 8:30 a.m. on Century Oaks Terrace in the Domain shopping center. Race organizers describe the course as flat and fast.

Participants get chips, hot sauce and goodie bags.

Proceeds benefit JDRF, formerly known as the Juvenile Diabetes Research Foundation, which works to improve lives and find a cure for Type 1 diabetes. Since 2012, Schlotzsky’s has raised more than $500,000 for JDRF.
