Gear up your buns, folks.

This year’s Schlotzsky’s Bun Run, where teams can earn honors for Austin’s Fittest Buns, Austin’s Fastest Buns, Austin’s Best Lookin’ Buns and Austin’s Most Generous Buns, is set for Sunday at The Domain.

Last year, the race, long a harbinger of springtime in Austin, shifted to a fall date. It also moved from downtown to the Domain, and announced proceeds would benefit JDRF, formerly known as the Juvenile Diabetes Research Foundation.

The race stays at the Domain this year, and again benefits JDRF, which works to improve lives and find a cure for Type 1 diabetes.

Besides the timed 5K run, with cash prizes for the top male and female winners, there’s a Kids K race for children 12 and under and a team challenge. Dogs can get in on the action too, running alongside their owners to compete for the title of Fastest Dog in Austin.

Race organizers describe the course as flat and fast.

The kids race starts at 8 a.m. and the 5K starts at 8:30 a.m. at 11401 Century Oaks Terrace.

Participants get chips, hot sauce and goodie bags. A special Kid’s Korral with fun activities including face painting and special treats is also planned.

Since 2012, Schlotzsky’s has raised more than $500,000 for JDRF.
