The 56th annual Algonquin Founders’ Days festival parade was held Saturday, with a “Turn of the Century” theme.

New to the festival this year is a car show from 3 to 7 p.m. today on historic Main Street.

“Sunday afternoon, after the park closes, there’s not much for people to do as they’re waiting for the fireworks. We thought we would give them something to keep them occupied until the fireworks start,” Founders’ Days Board President Alan Kirk said.

Families can test their athletic mettle competing in the Founders’ Days Family Olympics at 1:30 p.m. today at Towne Park, 100 Jefferson St. The games consist of multiple competitions, including a mummy relay race and a three-legged race.

“Picture 8-year-old kids wrapping their parents to look like mummies,” board secretary Sue Bazdor said. “It’s absolutely hysterical. They do an awesome job.”

Founders’ Run-Walk registration begins at 7 a.m. today at Algonquin Middle School, 520 Longwood Drive, with the 1-mile run starting at 8 a.m., the 10K and 5K starting at 8:30 a.m. and the 5K walk starting at 8:35 a.m. The registration fee for the 10K and 5K is $25. For the 1-mile run, it’s $15.

Festival admission fee is $2 for adults and $1 for kids ages 5-12 from noon to 5 p.m. today.
