Mark Rotundo probably could describe every twist and turn of the well-known 10-kilometer running course in Lake in the Hills.

The 32-year-old resident lives right off the course that starts near the AMC movie theater at the intersection of Randall Road and Acorn Lane. When the annual Run Thru the Hills race comes each April, Rotundo is sure to sign up.

“It’s like my neighborhood course,” said Rotundo, who has won the 10K race the past three years. “It’s probably one of the most challenging courses you can get for a 10K road race.”
